How to check for Unauthorized Activity on Your Email Account





Do you suspect that your email account is under attack? Do you want to maintain total security of your email account and make it 100% hack proof? Well, Some times our email account might have got hacked and we may not be aware of that. We may believe that our email account is safe, but in reality our private and confidential information may be falling into the hands of a third person.


Here are some signs of  unauthorized activity on an email account.

1. Your new emails are marked as Read even if you’ve not read them.

2. Your emails are moved to Trash or even permanently deleted without your notice.

3. Your emails are being forwarded to a third party email address (check your settings->forwarding).

4. Your secondary email address is changed.

If you come across any of the above activities on your email account, then it is a clear indication that your email account is hacked.

Additional Security Features in Gmail to ensure the Safety of your Account

Gmail provides an additional security feature to protect your email account through the means of IP address logging. That is, Gmail records your IP address every time you login to your Gmail account. So, if a third party gets access to your account then even his/her IP is also recorded. To see a list of recorded IP address, scroll down to the bottom of your Gmail account and you’ll see something like this.


You can see from the above figure that Gmail shows the IP address of last login (last account activity). You can click on Details to see the IP address of your last 5 activities. If you find that the IP listed in the logs doesn’t belong to you, then you can suspect unauthorized activity.

Steps to be carried out to stop unauthorized activity on your email account

If you feel/suspect that your account is hacked then you must immediately take the actions mentioned below

1. Change your Password

2. Change your security question.

2. Remove any third party email address (if any) to which your account is set to forward emails.

3. Make sure that you can access the email account of your secondary email address.

4. Also change you secondary email password and security question.

This ensures that your account is safe from future attacks.

How to Test the Working of your Antivirus – EICAR Test

Have you ever wondered how to test your Antivirus software to ensure it’s proper working? Well here is a quick and easy way to test your antivirus. The process is called EICAR test which will work on any antivirus and was developed by European Institute of Computer Antivirus Research. This process can be used by people, companies and antivirus programmers to test the proper functioning of the antivirus/antimalware software without having to deal with the real computer virus which can cause damage to the computer. Here is a step-by-step procedure to test your antivirus.

1. Open a notepad (New Text Document.TXT) and copy the following code exactly onto it, and save the notepad.

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

2. Rename the file from New Text Document.TXT to myfile.com

3. Now run the antivirus scan on this myfile.com file.

If the antivirus is functioning properly on your computer, then it should generate a warning and immediately delete the file upon scanning. Otherwise you may have to re-install your antivirus.

NOTE: Most antivirus will pop-out a warning message in the Step-1 itself.

You can also place the myfile.com file in a ZIP or RAR file and run a scan on it so as to ensure whether your antivirus can detect the test string in the compressed archive. Any antivirus when scanning this file will respond exactly as it will do for a genuine virus/malicious code. This test will cause no damage to your computer even though the antivirus will flag it as a malicious script. Hence it is the safest method to test the proper functioning of any antivirus.

Changing ANY user's password without having to know the existing password

This tweak gives a user the opportunity to use it for good or bad. It enables the user to re-password any account
without having to know the existing password and also shows you every account that exists on the machine
(even the ones that are hidden). This is a good tool to use if you forgot a password to say your administrator account
and you needed to be logged into the admin account for any reason.

To view all of the user accounts:

1) While logged onto the computer, click on Start>Run>and type in CMD.

2) From the command prompt window, type in net users. This will show you every account that is made onto the computer
whether it is hidden or not.


To change an account password:

1) While logged onto the computer to an account that has administrative rights, click on Start>Run>and type in CMD.

2) Type in net user then the name of the account then * and press enter. heres an example: net user administrator * or
net user "mehra" * . Put the name in quotes if it contains spaces.



3) From there it should ask for a new password. Type in your new password (type very carefully - the command window won't display what you type) and once more to confirm it.
 If you get the message that the command succeeded successfully you're all set!!

Disable unnecessary services to free system resources

Services are programs that run when the computer starts up and continue to run as they aid the operating system in functionality.  There are many services that load and are not needed which take up memory space and CPU time.  Disabling these services will free up system resources which will speed up your overall computer experience.  I  recommend that you sort through the list and read the descriptions to decide if you need that service depending on what you want to do with your computer.  Remember, you can always turn the service back on if you find that you need it in the future. Below is the procedure to turn off a service.
  1. Click the start button.
  2. Select run from the bottom of the right column.
  3. Then type services.msc in the box and click ok.


     4.Once the services window has loaded we are ready to turn off unneeded services.









      5. For instructional purposes we are going to turn off the DHCP client service.
     
      6. select the service from the list of services running and right click on it
     
      7. now click on the properties option





       8.Once the properties windows has loaded locate the Start up type drop down box and select disable.


      
       9.Then just click ok and the next time the computer starts the service will not be loaded.



you can see that DHCP CLIENT service has been stopped ,similarly you can disable all the unwanted services from the pool of services that are listed in the table mentioned above.

OpenDNS: Speed up your web browsing experience

When you type in a domain name such as http://techieassist.blogspot.com/  in your browser the computer must resolve the friendly name into an IP address of the server to download the web page and supporting files. Windows uses a DNS (domain name system) server to lookup this information.  By default, Windows uses your ISP’s DNS server.  Depending on your provider, the performance of their DNS resolving server varies.  Some large national providers are known to provide unreliable and slow DNS servers.
The performance of the DNS server you are using is one component that affects the speed of your internet browsing.  Since each domain name you type in must be resolved into an IP address, the amount of time that takes will delay the loading of any web page.  Some users with overloaded ISP DNS servers can see delays in multiple seconds before web pages start to load.
OpenDNS provides free alternative DNS servers that anyone can use with any internet provider.  Unlike many national internet providers, OpenDNS’s DNS servers are very fast and reliable.   Using OpenDNS servers instead of your ISP servers will help you speed up your internet browsing by cutting down on the delay between resolving a domain name and getting the IP address so your browser can start loading the web page.

Configuring your computer to use OpenDNS servers instead of your ISP’s is a simple change that works in both Windows XP and Windows Vista:

  1. Click on the Start Button and type in ncpa.cpl and hit Enter.  In Windows XP Click on the Start Button, click Run and then type in ncpa.cpl
  2. Right click on your active network connection that you use to connect to the Internet and select Properties.
  3. On the Networking / General tab, select Internet Protocol (TCP/IP) (version 4 on Windows Vista & 7) and hit Properties.
  4. On the properties screen, select Use the following DNS server addresses and then type in 208.67.222.222 in the preferred and 208.67.220.220 in the alternate boxes.

  1. Hit OK twice and you are finished.
experience the speed of your web browsing  and do comment about it.

Tweaking XP: To Speed Up Your Internet Access



Tweaking your Internet connection for speed
 
Almost every computer user has different Internet connection conditions. Some users have very high-speed connections, while others have slow connections. Some users have high-speed connections using cable-based technologies, while others have high-speed connection through DSL-based technologies. On top of these differences, some are located farther away from their local network switching station than others and have a higher latency (delay) on their connections because of the distance the data has to travel. All of these different connection conditions make every user unique.
The TCP/IP protocol settings can be optimized for best speed under each of these situations. By default, Windows XP has these settings set in a "one size fits all" approach. As I mentioned earlier, Windows has to be abstract in certain areas because of its broad user base. Because of this approach, many users can fine-tune their settings to be optimal for their connection conditions. Doing so will optimize the data transferred so your network connection will be more efficient, leading to high speeds.
With a little help from some fine online tools and software programs, you can test your Internet connection and decide what needs fine-tuning. The process of tweaking your Internet connection is not always easy, but it is doable.
Caution: Before going any further, you are strongly advised to create a system restore point, so that if things go wrong, which is not very likely, you will have a backup.
The next step in the tweaking process is to get all of the software that is needed. The main software program that you will use is called CableNut, which is developed by CableNut Software and is available for free at www.cablenut.com. CableNut is a great program that allows users to edit their Internet settings easily. Visit their Web page and download and install the latest copy. 

Calculating settings for CableNut
 
Once you have downloaded CableNut, you are ready to start getting information to use with the program. The first value that you will need to calculate is the latency of your connection when it is active. To do this, you will use the trace route command built into Windows XP. Follow these steps to get the latency value to use for your connection: 
  1. First, open up a Command Prompt window. This can be done by clicking the Start Menu and selecting Run. Then type cmd in the text box and click the OK button.
  2. Once Command Prompt is loaded, you are ready for the next part. Because you will need to test your connection when it is active, you will need to find something large to download that will run the duration of the test, which will be approximately 30 seconds. I recommend that you head over to www.microsoft.com/downloads and find some huge file, such as the .NET SDK framework, which is over 100,000 KBs. For the test, you want a file big enough so it will be downloading throughout the whole test. Those of you on a dialup connection can pick a much smaller file than those on a high-speed connection. 
  3. Once you have your download test file picked out, start the download and switch back to the Command Prompt window. In that window, type tracert www.tweakxp.com. During the test, you will see many times displayed in milliseconds. After the test finishes, pick the highest time, as shown in Figure 11-12. This is the number that you will use as your latency. Also, feel free to cancel the download after the test is finished. 


Entering the latency value into CableNut
 
Now that you have the latency value calculated, you are ready to enter this information into a great online CableNut settings calculator written by Joe Zeiler. Open up your Web browser and visit www.j79zlr.com/cablenutXP2k.php (the URL is case-sensitive!), then follow these steps to get the values to enter into CableNut: 
  1. Once you have opened up the site, the first part of using the settings calculator is to select your connection type from the drop-down box.
  2. Next, you will have to do a little research and find out exactly what your upload and download speeds should be for your Internet connection. I had to contact Comcast, my ISP, to find out the exact values, because the values are not always advertised. Once, you get those values, make sure that they are in kilobits per second and not kilobytes per second (KB= kilobytes; Kb= kilobits), then enter them in the corresponding text boxes on the Web page. 

  1. Enter the latency value that you calculated earlier into the latency text box on the Web page and then click the Calculate button.
  2. After you hit the Compute Settings button, scroll down and you will see the values that were calculated. Now, you are almost done. Continue scrolling down until you see a button labeled CCS File Generator under the Cablenut setting files section. Click that button and a new window will pop up with some text in it. Make sure that you have any pop-up blockers disabled when you are using the calculator.
  3. Use the mouse and select all of the text and numbers that are displayed in the pop-up window. Right-click the mouse and select copy to copy all of the text on the page to the clipboard.
  4. Now open up Notepad from the Accessories folder. In the blank Notepad window, paste the contents of the clipboard by right-clicking the white background and selecting Paste.
  5. Once Notepad is displaying the information that you copied from the pop-up window, all that is left is to save the file in the CableNut format. To do this, click the File menu bar item and select Save As. Then in the Save As Type drop-down box, select All Files. Key in myCableNutSettings.ccs in the file name text box. Specify the Save location, such as the desktop, and click the Save button.
You are now finished with the calculations that will optimize your Internet connection. That wasn't too hard now, was it? 

Using CableNut to adjust settings
 
Now that you have created your CableNut settings file, or will be using the 56K settings file, you are ready to start using CableNut. Follow these steps to import the new optimized settings into your system: 
  1. Start up the CableNut application by opening the Start Menu and browsing to the CableNut folder and selecting the adjuster application.
  2. When CableNut has loaded, click the File menu bar item and select Open Custom Settings File. Navigate to where you saved your settings file, or if you are a 56K user, use the file that is on the companion CD, called 56K_CableNut.ccs, and then click the Open button.
  3. Now you will see the information boxes for all of the different parameters filled with your connection-specific information, as shown in Figure 11-13. The last step is to click the Save to Registry button and you are finished. After you click the Save button, reboot, and your new settings will be in effect. 



Caution:
According to www.j79zlr.com/cablenutXP2k.php, some of the CableNut settings can cause problems for a small amount of DSL customers. If you are experiencing network problems after optimizing your connection, use System Restore to revert to your last restore point. You may try the settings again, but blank out the MaxNormLookupMemory, MaxFreeTcbs, MaxHashTableSize, and FastSendDatagramThreshhold fields before applying. If you continue to have problems, or if you have problems with the directions and still want to optimize your connection, a great forum to get help on this topic is at www.broadbandnuts.com,

Tweaking XP: To Speed Up Your Network



This excerpt is from a book, Hacking Windows XP, shows you how to tweak the Windows XP System Registry settings to improve network and Internet speed.
 
The speed of your network connection doesn't just depend on the speed of your hardware. Windows is an operating system that is designed to work on a variety of different hardware and network setups. Because of the abstract nature of the operating system, it cannot be optimized for user-specific hardware setups.
Depending on the type of network connection you have, you might be able to tweak your connection so that the speed of your Internet, as well as your local area network, will be faster. By hacking the System Registry and editing the TCP/IP parameters, you can fine-tune the values to take advantage of more reliable, faster Internet connections, such as DSL and cable. 


These next sections will guide you through the steps of increasing both the speed of your local area network and your Internet connection. 


Does your computer slow down when you browse your local area network and connect to other computers that are sharing data? One of the most common causes of this slowdown is a feature of Windows Explorer that looks for scheduled tasks on remote computers. This effort can take some time on some computers and can really slow down your browsing. The window with which you are browsing the network may appear to freeze momentarily, as the system is waiting for a response from the remote computer.
Although this problem is a complex one, the solution is very simple. Instead of having to wait for the remote scheduled tasks, which is useless information to anyone who is not a system administrator remotely configuring scheduled tasks, you can disable this feature. 
In order to do this, you will have to hack the System Registry and delete a reference to a key so that this feature will not be loaded. To do this,
follow these steps: 

  1. Open up the Registry Editor by clicking the Start Menu and selecting Run. Then type regedit in the text box and click the OK button.
  2. Once the Registry Editor has loaded, expand the HKEY_LOCAL_MACHINE key.
  3. Next, expand Software and then Microsoft.
  4. Locate Windows and expand that as well.
  5. You will want to be editing the main system files, so expand CurrentVersion.
  6. Because this feature is a feature of the Windows component known as Explorer, expand the Explorer key.
  7. Next, you will want to modify the remote computer settings, so expand the RemoteComputer key and then expand the NameSpace key to show all of the features that are enabled when you browse to a remote computer.
  8. In the NameSpace folder you will find two entries. One is "{2227A280-3AEA-1069-A2DE-08002B30309D}" which tells Explorer to show printers shared on the remote machine. The other, "{D6277990-4C6A-11CF-8D87-00AA0060F5BF}," tells Explorer to show remote scheduled tasks. This is the one that you should delete. This can be done by right-clicking the name of the key and selecting Delete. 

Tip:
If you have no use for viewing remote shared printers and are really only interested in shared files, consider deleting the printers key, "{2227A280-3AEA-1069-A2DE-08002B30309D}", as well. This will also boost your browsing speed.
Once you have deleted the key, you just need to restart and the changes will be in effect. Now your network computer browsing will be without needless delays

Disabling unneeded protocols
With every computer comes programs installed that you do not need. As with extra programs taking up space, extra protocols are just wasting your network connection and can actually slow it down. How is this possible? By default, a few different protocols are installed on your computer to allow for maximum compatibility with other computers on a network; these protocols each require bandwidth to operate. Most users will not use too many protocols, and their computers will use up a portion of their connection as they respond and transmit information for these protocols.
Additionally, with extra protocols installed on your network adapter connected to the Internet, you increase your risk of security-related problems. One of the most common risks for broadband users is that they have the Client for Microsoft Networks networking protocol enabled on their connection. This protocol allows everyone in their neighborhood to connect to the users' computers and view any files that they may be sharing. This fact alone should be a good enough reason for you to turn off the extra protocols. But with them disabled, you will also save a little bandwidth as well.
Viewing protocols on your network adapters
Viewing the protocols installed and active on your various network adapters is easy. Just follow these quick steps and you will be viewing them in no time: 


  1. Right-click the My Network Places icon on the desktop or in the Start Menu and select Properties. If the My Network Places icon is not in either of those locations, then go to the Control Panel and click the Network Connections icon that is shown under the Classic view.
  2. Next, right-click the network adapter with which you want to view the network protocols and select Properties.
  3. This will bring up a list of the protocols installed as well as active on your adapter, as Figure 11-11 shows. The protocols that are installed but not active are indicated by the absence of a check in the checkbox.

Disabling a specific protocol
Now that you have the list of installed and active protocols on your screen, you are ready to disable a protocol. To do so, just click the check box to remove the check. Then click the OK button and the protocol is no longer active on the network adapter.
I highly recommend that you disable all protocols except for the TCP/IP protocol (also referred to as the Internet Protocol). Doing so will optimize your adapter for speed and security. 
  


Be aware that if you remove the Client for Microsoft Networks protocol and the file-sharing protocol, you will no longer be able to share your files. Additionally, you will no longer be able to connect to remote computers to view their shared files.
Also keep in mind that if you have multiple adapters in your machines, such as a wireless adapter, a wired network adapter, and a dialup modem, you will have to repeat the preceding instructions for each adapter.

GigaTweaker : improve your windows 7 experience



GigaTweaker is a Windows 7 Tweaks software meaning it has been specifically designed for that Microsoft OS. It works with both the 32-bit and 64-bit edition of Windows 7. The tweaking software needs installation but can be used as a portable software program  afterward



The interface of GigaTweaker provides access to the five main tweaking categories Administration, Display, Customization, Communication and Maintenance which all contain various subcategories like Security, Restrictions, Memory Management or Visual Effects.

  • Administration: System, Security, Files and Drives, Restrictions, System Information
  • Display: Explorer and Start Menu, Visual Effects
  • Customization: System, Optimization, Memory Management, Context Menu
  • Communication: Network, Internet Explorer
  • Maintenance: Startup Manager, Uninstall Manager, Windows Utilities

Selecting a category on the left will display the tweaks that are provided on the right, often in a tabbed interface.

Most tweaks that can be applied are either self-explanatory (Disable Control Panel or Remove the shortcut arrow) or contain a short explanation what the tweak is all about.
GigaTweaker will indicate to the user if a system restart is needed to apply some of the tweaks that have been made.

There are well over one hundred tweaks available. The Windows 7 tweaker asks the user to create a system restore point on startup. Cautious users should create one to be able to return to the previous system state if something goes wrong in the tweaking session.

GigaTweaker is a portable software program for the Windows 7 operating system. It can apply lots of tweaks in Windows 7 that would take longer (and knowledge) to apply manually.

    What Are the Differences between 64-Bit and 32-Bit Processors?



    To understand why 64-bit operating systems are a logical step in the evolution of the PC, consider this background information. More often than not, the maximum size of the physical memory on a computer is less than the amount needed for all running programs. This is especially true when multiple processes or applications execute simultaneously. The solution for this is that programs store some of their data on the hard drive and copy it back and forth to physical memory as needed.


    This solution is often referred to as “virtual memory,” in which the computer simulates having large amounts of contiguous physical memory. A paging table is responsible for moving segments of virtual memory into physical memory as necessary. If the amount of memory demanded by all running processes exceeds the available physical memory (RAM), the paging table stores low-priority processes on the hard drive in the page file, which is much slower than RAM. When the user needs these processes, the page table re-maps them into physical memory, where the user can access them at high speeds (see Figure 1). The total number of addresses available in the virtual memory – the total amount of data the computer can keep in its working area for applications – is determined by the width of the registers on the computer processor.
    Figure : The paging table moves segments of virtual memory into physical memory as needed to provide more memory to running processes.


    Until recently, almost all consumer PCs used 32-bit processors. The bit size of a processor refers to the size of the address space it can reference. A 32-bit processor can reference 2^32 bytes, or 4 GB of memory. These 32-bit processors were standard at a time when 4 GB was thought to be more than enough memory space for software applications on Windows. When a process, such as running a program, is created on an x86 Windows computer with a 32-bit processor, the operating system allocates its 4 GB of virtual memory, irrespective of the actual physical memory installed on a system. Half of that allocated memory is user-accessible memory, while the other half is for kernel processes such as drivers. Modern computing systems increasingly confront the 4 GB ceiling thanks to memory-intensive applications and the need to store multiple processes in memory simultaneously.



    In 2003, AMD released the first widely accepted 64-bit processor aimed at consumers, the Athlon 64, and coined AMD64 as the name for the new instruction set. Microsoft refers to the instruction set as x64, which parallels the widely accepted x86 nomenclature used for the instructions that run on most 32-bit processors. 
    Processors capable of referencing larger address spaces provide the opportunity to use more physical memory than ever before, potentially reducing the overhead spent moving processes in and out of physical memory. The 64-bit processors are theoretically capable of referencing 2^64 locations in memory, or 16 exabytes, which is more than 4 billion times the number of memory locations  32-bit processors can reference. However, all 64-bit versions of Microsoft operating systems currently impose a 16 TB limit on address space and allow no more than 128 GB of physical memory due to the impracticality of having 16 TB of RAM. Processes created on 64-bit versions of Windows are allotted 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB.
    To summarize, the ability of Windows Vista and Windows 7 x64 Editions to add address more memory space than previous versions of Windows helps minimize the time spent swapping processes in and out of memory by storing more of them in RAM.

    Everything: A new and 20 times faster search utility then basic search of windows

    The Everything application was designed to be a fast folder and file name search engine for Windows. Unlike Windows search "Everything" initially displays every file and folder on your computer (hence the name "Everything"). You type in a search filter to limit what files and folders are displayed.


    Here are some key features of "Everything":

    · Small installation file
    · Clean and simple user interface
    · Quick file indexing
    · Quick searching
    · Minimal resource usage
    · Share files with others easily
    · Real-time updating





    everything options:






    we can specify the drive to begin the search in



    we can even exclude certain location to skip the search in



    windows 7 : Shake it

    Quickly minimize all other open windows in Windows 7 by shaking the only one you want displayed.


    While working with multiple applications and windows in Windows 7, have you ever found the screen too cluttered? Perhaps you're mainly working in one application but want the others easily available, minimized to the taskbar.


    In other versions of windows this task required a couple of steps. Right-click the taskbar and minimize all windows, then click on the taskbar button representing the window you want remaining open. But in Windows 7 there's another way...

    Left-click on the title bar of the window you want remaining open and keep the mouse button help down. Now "shake" your mouse pointer quickly and the other windows will minimize to the taskbar, keeping the shaking window open.



    before


    after shaking the notepad , it remains active on screen rest others are minimized to the task bar



    Foxit pdf reader: small, fast and rich

    Foxit Reader is a free PDF document viewer, with small size, fast launch speed and rich feature set. Its core function is compatible with PDF Standard 1.7. In the past, you've had to download a huge PDF reader from another software company, go through a lengthy installation process and wait for an annoying splash window to disappear just to open a PDF document.
    To put it gently, Adobe Reader is a real pain in the hindquarters. It's monstrously large, slow to load, and includes many features most users will hardly ever need. Foxit PDF Reader 3.0 kills the bloat and throws in some useful features, such as multimedia support and content-sharing options, while still allowing you to quickly access your PDFs.
















    Here are some key features of "Portable Foxit Reader":

    · Breezing-fast: When you run Foxit Reader, it launches instantly without any delay. You are not forced to view an annoying splash window displaying company logo, author names, etc.

    · Annotation tool: Have you ever wished to annotate (or comment on) a PDF document when you are reading it? Foxit Reader allows you to draw graphics, highlight text, type text and make notes on a PDF document and then print out or save the annotated document.

















    · Text converter: You may convert the whole PDF document into a simple text file.

    · High security and privacy: Foxit Reader highly respects the security and privacy of users and will never connect to the Internet without users' permission. While other PDF readers often silently connect to the Internet in the background. Foxit PDF Reader does not contain any spyware.

    Ophcrack:The ultimate Windows password cracker


    1. Visit the Ophcrack Website

    Ophcrack LiveCD 2.3.1 is a completely self contained, bootable version of Ophcrack 3.3.1 - the easiest and most effective tool that I've ever found to "crack" your forgotten Windows password.

    Ophcrack is a free software program that recovers passwords so the first step you'll need to take is to visit Ophcrack's website. When the Ophcrack website loads as shown above, click the Download ophcrack LiveCD button.

    2. Choose the Correct Ophcrack LiveCD Version





    After clicking the Download ophcrack LiveCD button in the previous step, the webpage above should display.

    Click the button corresponding to the operating system of the computer you'll be recovering the password on. The operating system of the computer you're using right now doesn't matter.

    For example, if you've forgotten the password on a Windows 7 or Windows Vista computer, click on ophcrack Vista LiveCD. If you've forgotten the password on a Windows XP computer, click on ophcrack XP LiveCD.

    3. Download the Ophcrack LiveCD ISO File



    Ophcrack LiveCD should begin downloading automatically. The download is in the form of a single ISO file.

    If prompted, choose to Download File or Save to Disk - however your browser phrases it. Save the file to your Desktop or another location that's easy to locate. Do not choose to Open the File.

    The size of the Ophcrack LiveCD software you're downloading is fairly large. The Windows 7 / Windows Vista version is 496MB and the Windows XP version is 415MB.

    4. Burn the Ophcrack LiveCD ISO File to a CD



    After downloading the Ophcrack LiveCD software, you'll need to burn the ISO file to a CD.
    Note: If the ISO file is not burned correctly, Ophcrack LiveCD will not work at all.

    After burning the Ophcrack LiveCD ISO file to a CD, go to the computer that you can't get in to and continue to the next step.

    5. Restart With the Ophcrack LiveCD Disc In Your CD/DVD Drive




    The Ophcrack LiveCD disc you just burned is a "bootable" CD, meaning it contains a small operating system and software and can be ran independent of the operating system on your hard drive. This is exactly what we need in this situation because you can't access the operating system on your hard drive right now (Windows 7, Vista, or XP) due to not knowing the password.

    Insert the Ophcrack Live CD disc into your CD/DVD/BD drive and restart your computer.

    The initial screen you see after restarting should be the same one you always see immediately after starting your computer. There may be computer information like in this screenshot or there may be a computer manufacturer logo.

    Ophcrack LiveCD begins immediately after this point in the boot process, as shown in the next step.

    6. Boot to the Ophcrack LiveCD Disc


    After the initial startup of your computer is complete, as shown in the previous step, the Ophcrack LiveCD menu should display.

    You don't need to do anything here. Ophcrack LiveCD will continue automatically after the Automatic boot in x seconds... timer at the bottom of the screen expires. If you'd like to advance the process a little faster, feel free to hit Enter while Ophcrack Graphic mode - automatic is highlighted.

    Don't See This Screen? If Windows started, you see an error message, or you see a blank screen, then something went wrong. If you see anything other than the menu screen shown above then Ophcrack LiveCD did not start correctly and will not recover your password.

    Are You Booting to the CD Correctly?: The most likely reason that Ophcrack LiveCD might not be working properly is because your computer is not configured to boot from the CD you burned. Don't worry, it's an easy fix.

    just go to your bios screen and set cdrom as your first boot device.

    7. Wait for Ophcrack LiveCD to Load



    The next screen consists of several lines of text that quickly run down the screen. You don't need to do anything here.

    These lines of text are detailing the many individual tasks that SliTaz (a Linux operating system) is taking in preparation for loading the Ophcrack LiveCD software program which will recover the passwords encrypted on your hard drive.

    8. Watch for Hard Drive Partition Information to Display



    The next step in the Ophcrack LiveCD boot process is this little window that appears on screen. It may appear and disappear very quickly so you could miss it, but I wanted to point it out because it will be a window that runs in the background that you may see.

    This message is simply confirming that a partition with encrypted password information on it has been found on your hard drive. This is good news!

    9. Wait for Ophcrack LiveCD to Recovery Your Password



    The next screen is the Ophcrack LiveCD software itself. Ophcrack will attempt to recover the passwords for all of the user accounts that it can find on your computer. This password cracking process is completely automated.

    The important things to look for here are the accounts listed in the User column and the passwords listed in the NT Pwd column. If the user account you're looking for isn't listed, Ophcrack didn't find that user on your computer. If the NT Pwd field is blank for a particular user, the password has not been recovered yet.

    As you can see in the example above, the passwords for the Administrator and Guest accounts are listed as empty. If you were cracking a password for a user that Ophcrack shows as empty, you now know that you can log on to the account without a password at all, assuming that the user account is enabled.

    Look toward the bottom of the user list - see the Tim user account? In under one minute, Ophcrack recovered the password to this account - applesauce. You can ignore any other accounts you're not interested in recovering the passwords for.

    After Ophcrack recovers your password, write it down, remove the Ophcrack LiveCD disc from your optical drive and restart your computer. You don't need to exit the Ophcrack software - it won't harm your computer to power it off or restart it while it's running.

    In the next step, you'll finally get to log on to Windows with your new password!

    Note: If you do not remove the Ophcrack LiveCD disc before you restart, your computer will likely boot from the Ophcrack disc instead of your hard drive.

    10. Logon to Windows With the Ophcrack LiveCD Recovered Password

    Now that your password has been recovered using Ophcrack LiveCD, simply enter your password when prompted after booting your computer normally.
