Hello! I am sincerely hoping that someone is able to assist me, because I am about ready to pull my hair out. I have Windows 8 Pro 64-bit installed on my pc, Upgraded from Windows 7 Professional. Both copies of Windows were legitimately purchased and activated. Now, however, Windows 8 is telling me that it is not activated. The only thing that I did on the pc is I installed and ran a program called System Mechanic, and soon after running it, Windows 8 began saying it was not activated. I did some googling and I attempted to do the whole "run->slui 3" bit but it gave me the error message: "error 0x80070424. The specified service does not exist as an installed service." Not really sure if this information is enough to diagnose the problem, but any and all advice will be greatly appreciated! Thanks ahead of time!
