Weird thing happened to me just a few moments ago.. I rec'd a message saying my copy of windows isn't geniune...??? EVEN THOUGH I have a legit retail copy installed.. The message came upon startup.. It was also present in Microsoft Essentials.. Anyway i clicked a check for validation (even though this was done back in October when i first PURCHASED my retail copy) It went off and said it had passed. So something is possibly up with their validation servers. Anyone else had this prob? I'm about to reboot and see if the message comes back.
