Hello, I am having problems with my serial, It was working great, untill unexpectedly A message popped up, bottom right corner Saying it wasn't genuine, build 7601. Then I thought, I'll try Windows Loader, ran as admin, installed, The Certificate wasn't succesfully installed for some reason? Then I checked my OEM serial thingy, and the HP one is the MHFPT and so was mine, Did microsoft just blacklist the HP key?
I got it activated using windows loader, It worked perfectly, but I don't know how it was not genuine, then I system restored to back to when it worked, still didn't work, + more info, i deleted all prev windows restore's, because I was cleaning the computer... But I'm pretty sure if I reinstall windows it might go away, but I want to keep all my files.
