If you forgot your password of your windows XP here is a simple solution.
- Restart you computer
2.When booting, press F8 and select "Safe Mode"
3.After getting to the user menu. Click on a user and this time it will not ask you for a password
4.Go to Start>Run and type CMD .
5.At command prompt type in cd C:WindowsSystem32, (Where C put your system's HD letter,I am assuming C is your System/Windows Drive)
6.For safety purposes first make a backup of your Logon.Scr file.. You can do this by typing in Copy Logon.scr Logon.bak
7.Then type copy CMD.EXE Logon.scr
8.Then type this command, I will assume that you want to set Administrator's password to NewPass
9.Now, type this in net user administrator NewPass - You will get a message saying that it was successful, this means Administrator's new password is NewPass
- Restart the PC and you will login as Administrator (or whatever you chose to reset) with your chosen password.
