How to Fix a Bad Code Key in Windows XP

Microsoft Windows XP disables operating system availability when a bad key is found. This happens after you install the service packs released by Microsoft to fix some of the security and bug issues. Even though the operating system is locked, you can fix the problem by inserting a new Windows XP key into the reactivation window included with the operating system. Once activated, the operating system is unlocked and you can return to normal computer activity.

Things You'll Need

• New Windows XP key

Instructions

1. Click "Start" and select "Run." Enter "C\system32\oobe\msoobe.exe /a" into the text box and press "OK." This opens the screen where you can re-enter a new Windows XP key.

2. Check the box labeled "Yes, I want to telephone a customer service representative to activate Windows." Click "Next."

3. Click the button labeled "Change Product key." This opens a new window with a text box where you enter the new Windows XP key.

4. Click "Update." Click "OK" to close the window. The product key is changed. Reboot the machine for the changes to take effect.
