I have XP set up as a guest on my system. At first useage after a whopping download of 'required' security fixes the system prompted me to Activate the Software before I cold install other updates. I clicked on the Activate Windows icon and up popped a blue pop-up screen. It contained four small white squares with red crosses in them - akin to image place holders. Nothing further. I have tried microsoft support and they cannot help. Al they ask for is the first six numbers of my activation code - I do not have one as the process does not provide me with them! Any Ubuntian gurus to help with this issue. The copy expires without activation in a few days!!!
