Hey, Firstly i love display fusion, never had any problems with it and it's a great program. I have a pro license and such.
So today i booted up my computer, and it came up with the automatic download and install for the 3.1.9.1 update. So i did this and restarted after
However, on booting up, My screen went black and it states that windows was not genuine and asked me to get genuine now or continue. I continued and then sure enough, after getting through it, opened up my computer and checked and it had changed it to being genuine. Microsoft security essentials also stopped working until i told it to check the validity and then it started to work again.
I am 100% sure that my version of windows is genuine, and this is the first time it happened after rebooting the install for this update. I did nothing else before rebooting.
I havent tried rebooting again to see if this is a re occuring problem or just the one time install. So although it may not be a problem any more, it alerted me.
Thanks,
My computer specs, just incase.
Windows 7, 64 bit, Professional.
Intel core 2 E6750 @ 2.66ghz.
4Gb Ram.
Ati 5770 Graphics card.

I've rebooted and the issue didnt occur again. It's just rather strange. Might just be my computer as it's strange somedays.

And while you're at it scan your machines thoroughly - just in case.

I normally keep my computer well defended but did do a full scan after you adviced but nothing came up on any of my antivirus's ect.
But thanks anyway. I guess it was just being weird.
