					Reset Windows Password

Forgot your administrator password? This page provides step-by-step how
to reset your local Windows password. This only works for local user
accounts, however, not domain accounts.
The password recovery tool from this page is written by Petter Nordahl-
Hagen, and the original information, as well as the downloadable tool,
can be found from his website
Code:

. Per author's information, this tool should work for Windows
NT/2000/XP/Vista.

WARNING! Users who have EFS encrypted files on the Windows XP or Vista
computers will loose access to the EFS encrypted files after recovery of
your password.

The tool can be downloaded here

password in case you lost your password and cannot logon to Windows
again.
Use this trick at your own risks

      . The file contains the ISO CD image.

      .
II. Understanding the process:

    * You'll use the bootdisk created from the above steps to bootup your
computer, which you want to reset your administrator password.
    * You'll be asked for things like: which drive is the boot drive,
which path to the SAM file, etc.. but don't worry, detailed information
will be provided.
    * Once you have selected an account to reset the password, you'll
need to type in a new password; however, it is highly recommended to use
a BLANK password at this point, then you can change your password later
in Windows.
    * Follow the prompts to the end. You'll need to save the changes at
the end!

III. OK! Enough talking. Let's get started:

   1. Startup your computer with the bootdisk created above. You should
see a welcome screen following with a prompt:
      boot:
   2. Just wait, the bootup process will continute automatically. Then
you should see a screen similar to this:
      ================================================== =======
      . Step ONE: Select disk where the Windows installation is
      ================================================== =======
      ....
      NT partitions found:
      1 : /dev/sda1 4001MB Boot
      2 : /dev/sda5 2148MB

       Please select partition by number or
       a = show all partitions, d = automatically load new disk drivers
       m = manually load new disk drivers
       l = relist NTFS/FAT partitions, q = quit
       Select: [1]
   3. Notice the last line "Select: [1]" contains the [1] as default
since the tool detects the bootup partition is [1]. This might be
different on your own machine, but double-check with the information
shown under "NT partitions found:", the partition with the word "Boot"
should be selected.
   4. Hit Enter if the default partition is correct, or enter the number
for the boot parition then hit Enter. Here's what you should see next:
       ================================================== =======
       . Step TWO: Select PATH and registry files
       ================================================== =======
       ....
       What is the path to the registry directory? (relative to windows
disk)
       [windows/system32/config] :
   5. Notice the last line "[windows/system32/config]" contains the
default path, which was detected by the tool. If the path is correct, hit
Enter, or if you wish to enter a different path, enter it now and hit
Enter.
       Here're the paths for different versions of Windows:
       - Windows NT 3.51: winnt35/system32/config
      - Windows NT 4 and Windows 2000: winnt/system32/config
      - Windows XP/2003 (and often Windows 2000 upgraded from Windows 98
or earlier): windows/system32/config
   6. Once you hit "Enter" the following similar information should
display:
      -r-------- 1 0 0 262144 Jan 12 18:01 SAM
      -r-------- 1 0 0 262144 Jan 12 18:01 SECURITY
      -r-------- 1 0 0 262144 Jan 12 18:01 default
      -r-------- 1 0 0 8912896 Jan 12 18:01 software
      -r-------- 1 0 0 2359296 Jan 12 18:01 system
      dr-x------ 1 0 0 4096 Sep 8 11:37 systemprofile
      -r-------- 1 0 0 262144 Sep 8 11:53 userdiff

      Select which part of registry to load, use predefined choices
      or list the files with space as delimiter
      1 - Password reset [sam system security]
      2 - RecoveryConsole parameters [software]
      q - quit - return to previous
      [1]
   7. Hit "Enter" with the default option selected "[1]". You'll get the
next prompt similar to this:
