Open the Serial Key Changer by running ôXPProCorp-keyChanger.exeö; it will bring up a new window with a DOS based program.

After the serial keys have been generated you will be prompted with the following screen which letÆs you activate Windows.

From here you need to select, ôYes, I want to telephone a customer service representative to activate Windowsö û DonÆt worry, we donÆt actually do it. After choosing this option you will then be taken to the following screen.

It doesnÆt actually matter what country you choose from the Step 1 field, as we wonÆt be calling anyone. Ignore the rest and skip down to the bottom and click the Change Product Key button which will bring you to the following screen.

Now refer back to the Serial Key Changer program and simply choose one and type it into the New key field area as shown in the picture above. Once youÆve done that click the Update button. It will then proceed to update your serial key and bring you back to the Activate Windows by Phone screen. From here you can close this screen; your Windows serial key has been changed.

To confirm that your serial key has changed correctly to the one you choose from the Serial Key Changer Program you need to go ahead and open the Serial Key Viewer program by opening the file ôWindowsXP Product Key Viewer.exeö.
