Posting for those who have Windows 7, if you have it installed and you do constant updates I recommend you take a look at the updates and remove the new one that says something about Activation, probably the title it has is something like "Important update" but if you check the description you will find the stuff there.
I'm saying this for everyone it doesn't matter if you have a downloaded version or went to Best Buy to get it, Microsoft is known for making updates a pain in the ass, so if you want to install this update I just warned you that it may end up locking your system. Then you will have to call Microsoft for assistance, blah blah blah... xD
If it doesn't lock the system then congratulations!, keep updating windows! but just be careful LOL xD
In my case I always like to be careful when installing Microsoft stuff
, so I removed this update from my update list, and is what I recommend.
SeeYaa!
