Create a Windows XP user from a linux partition

Solution 1:

Well, there's this, which is for the Administrator.

You'll need to install chntpw and mount the Windows FS. Go to WINDOWS/system32/config.

Issue su -c "chntpw SAM" (or sudo, if that's your thing) and reset the password with the * (asterisk) character.

Reboot as the Administrator, do whatever you need to do, and change the Administrator's password back to something you'll remember.

Solution 2:

ophcrack will give you the password used for the account. Burn it (it's a live CD), boot it and you're done - it won't write to the disk at all, just read it and crack the password already being used.

Solution 3:

First thing you should try is booting up in safe mode. It usually gives you access to an account named "Administrator" which usually does not have a password set.

If that doesn't work, just reset it using the Ultimate Boot CD. The tool is called something like "NT Offline Password Changer." In addition to being able to reset the password, you now have a CD full of useful tools.

Also, The NT Offline Password Changer tool usually doesn't work if you try to change the password. Instead, blank the password (always works in my experience) and then change the password inside of windows.

Solution 4:

If you have access to any account with administrator privileges you can recover the password entirely within Windows itself.

Hit the Windows key and type Computer Management. When the new window opens, look in the tree on the left under Local Users and Groups and then Users. You should be able to see the account there. Right click on the account and choose Reset Password....
