Today, I got the error after Windows failed to validated one of my updates. My first reaction was to google solutions for the windows 7 error. Almost every solution I try didn't work. In fact it made the problem worse. Eventually I came across a solution that might have fix the error for good. What I did was download magic jelly bean and made sure software protection was turn on in services.msc. Guess what? It actually work the windows 7 error no longer appears on my PC. I can no use my PC without having to see the damn pop up activation every two seconds. This is the second time I was force "Windows is not genuine" error. So I have no idea how long this fix is going to work.
