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 (all the way out)
