To help maintain the security of your Windows XP system, you should change your XP Admin password on a regular basis.
Steps to Change Your XP Admin Password
Click the <Start> button located on the Windows Toolbar.
Click on the <Control Menu> amongst the other Start Menu items.
Double-click on the <User Accounts> icon.
Under the "or pick and account to change" section, select a User Account that has the sub-title, "Computer Administrator."
Select <Create a Password> if you haven't yet added one to your account or <Change my Password> if you have.
If you are adding a password to your account, move onto the next step. Under the <Type your Current Password> section, enter the password that is currently added to the Computer Administrator account.
Under the "Enter a New Password" section, enter in the password that you would like to add/change to. Re-enter the password in the "Type the New Password Again to Confirm" section; ensure that CAPSLOCK has not been enabled (unless that was your intention).
Under the "Type a word or phase to use as a Password Hint" section, enter in a good password hint.
Click <Create Password> or <Change Password> to reach completion.
NOTE: This method can only be followed if you currently have access to another Windows XP Computer Administrator account. If you have lost your Admin password entirely, please refer to How do I Recover my Windows Administrator Password
