Stop Password Expiration

After you have run Windows XP for a while, you may receive this message when you log on:"Your password will expire in 14 days.."

By default, Windows XP is set up with passwords which will expire after 42 days. 14 days in advance, Windows will start warning you of this fact. If you do not want your passwords to expire:

Go to Start > Run and in the Open: box type control userpasswords2
Select the Advanced tab in the User Accounts window

Press the Advanced button below the Advanced user management header
Select Users in the Local Users and Groups.

In the right pane, right-click the user name for which you want to change the
setting, and select Properties.

On the General tab, check Password never expires

Click Apply and OK, exit!
