This is strange one.. I reinstalled and activated windows xp about six months ago. Now for the last few days after I log on, a window pops in with a message, "you have 7 days to activate your windows, do you want to activate now" with two options yes or no either of which does nothing. Pressing 'yes' opens activation window with this message 'windows is already activated' while 'No' does nothing. This happens at very startup now. Any ideas whats gone wrong?
