As referenced in my post “Crack/Hack Any Windows XP Password” where I explained a hack to crack any Windows XP password, this is a small but very useful XP hacking tutorial in which I will emphasize the method used to change/hack a Windows XP administrator password if you don`t have access to admin account.
Just follow the steps given below.
1. Start–>Run–>lusrmgr.msc and press Enter or OK.
2. Then you will see two folders: Users & Groups. You need Users, then in this folder right click on Administrator–>Set New Password !
You can use this hack any Windows XP administrator account even when it is password protected. Just follow the hack and you will be able to bypass/hack password, and even change an administrator account password.
