Duncan's Key Reader and Changer


I created this application because I lost my Windows XP key. And being a programmer getting it from the registry as a base24 encrypted key wasn't hard. However getting it converted to a genuine key was a little harder. Now it can read and change Windows 2000, Windows XP Home and Professional and Windows Vista Home basic, Home Premium, Business and Ultimate Product Keys.

If you have an OEM version you can't use the key generated from this program. In this case you MUST use the Product Key provided on the computer case. Read the disclaimer carefully!


I found out that after Office 2000 the registration key was also stored as a base24 encrypted key. This application can read the key but Microsoft has not yet created a way to change this key. I will test removing the key and see how Windows responds. For now reading the key is paramount.

In the picture below you can see the application. Of course with edited dummy keys. Completely created in VB.net 2008.
