Because of the security features built into Windows XP, it is virtually impossible to get back into the system without the password.
You have several options to try and get around this problem.


If you have access to another user account with administrator rights, you can use that account to change the password
of the account that is locked out. You can also use the default Administrator account that is built into Windows XP.

First you need to boot the system into Safe Mode.
1.Restart your system.
2.When you see the blue Dell globe or screen, press the ( F8 ) key about 3 times a second.
3.You should get the Windows startup menu. Use the (Up or Down) arrow keys to highlight (SafeMode)
4.Press (Enter) on (Safe Mode), then press (Enter) on (Windows XP).
5.The system should boot to Safe Mode.

Once you are at the Account Log on Screen, click on the icon
for the user account with administrator rights, or click on the icon
for the administrators account.
Note: For Home the Administrator account isn't normally shown & in Safe Mode you have to press Ctrl+Alt+Delete keys twice to show.
For PRO you can do this in normal mode
