Now you need to run keyfinder.exe. This is a tool that can display your current Windows XP and Office key and makes it possible to change it. Click on the Microsoft Windows tab, then on Options -> Change Windows Key. Enter the key you generated using the keygen into the window popping up and click “change”.

After a few seconds the popup should close, your key is changed now.
Fix WGA
Now that your key is changed, make it look genuine to WGA. Therefore a tool called WGA fix is included. Open wga-fix.exe and click on “Yes”, don’t care about the German language.

In order to do this, go to Start -> Run…, type in “regedit” (without the quotation marks) and press Enter.
In the Registry Editor appearing, navigate to the subkey “HKEY_LOCAL_MACHINE \Software\Microsoft\Office\12.0\Registration“. There should be another subkey that looks somehow like this one: {92120600-0030-1234-0000-1000000FF5CE}
If there is more than one, find the subkey that has a GUID (data set shown on the right) inside with
ProductName=Microsoft Office 2007
If you found it, delete the entries DigitalProductID and ProductID by rightclicking and selecting delete or just pressing the “Del” key. Afterwards, you can close the Registry Editor and proceed to the next step.
