  • That question has a solution your problem. If you just delete a file, you'll break Windows. What you really want is to regain access to your computer, right? Is it really necessary to do that your way? – gronostaj Aug 11 '13 at 11:54

Windows passwords are stored at "C:\Windows\System32\config\SAM" file copy it to your HDD-2 then You can use Pwdump.exe .so you can see passwords as MD5-Hashed. then you can de-code them using online MD5 decoders or softwares.

  • No you can't because passwords and **USERNAMES** stored there. if you want to go to windows without typing password,you don't need HDD-2. you can get a windows xp live CD/DVD, then you can boot windows (at HDD-1, which you want to go in) from that CD. when boot process completed you can use cmd.exe which is on your live cd. then you can easily erase any user passwords using this command: "net user [USERNAME] [NEWPASSWORD]" – Amirreza Nasiri Aug 11 '13 at 11:48

By using Trinity Rescue Kit, I've saved many people their installation. It just deletes the password from the account, and nothing else is lost.

Trinity Rescue Kit Website

I can confirm it works perfectly for windows xp, vista and 7.

When booting this from a CD or USB, you should go for the option "interactive winpass"

press enter to continue on the first option; "Edit user data" Type the username of the account you want to edit and enter.

You'll get various options now. Press 1 for the first option ("Clear (blank) password").

Simply reboot and your user account will be without a password.

Simply deleting or renaming the SAM file doesn't work! But there are two methods for you.

Method 1: Copy the SAM file from this directory C:\windows\repair to c:\windows\system32\config, it will enable you to log in to Windows without a password.

Method 2: Boot from a password resetting bootable CD such as PCUnlocker, it enables you to remove forgotten Windows password easily.

Each of these methods has its strengths and weaknesses. But remember to make a backup of your SAM file before using any method above.
