Hello all. The starangest thing happened yesterday. My wife's laptop has been activated with 7 Ultimate via BIOS mod for over a year. Just yesterday a message popped up out of nowhere saying Windows is not genuine but the system properties still says it's activated. I've attached a couple of screen grabs to illustrate. Clicking reslove online also tells me I'm not genuine. I've found a few threads of people who've had similar problems but nothing I've found works. I've tried reinstalling the key and license file, rearming and then reinstalling the key and license file, and running Fix WAT. After each I've run %SystemRoot%\system32\Wat\WatAdminSvc.exe /run and visited hxxp://xxx.microsoft.com/genuine/validate and I am continuously told that I am not genuine. BTW, the key that I use is the Acer key from the thread found here: hxxp://forums.mydigitallife.net/threads/10370-Windows-7-OEM-SLP-Key-Collection so the key should be good. Attached is also the output from the MGA Diagnostic Tool. I hope someone can help me straighten this out. TIA.
