My colleague has bought a PC with original WIN7 Prof. 64-bit.
1 week was working without any problems, but now he gets these pop-up messages:
This computer is not running genuine Windows
I've tried already a lot of solutions, for example to call Microsoft and activate by phone, but still doesn't help.
If we try MGADiag.exe from:
then we get this:
Validation Code: 0x8004fe21
It seems to be a really serious problem with Microosft Update: KB971033.
Howto solve this problem?
