windows 7 *your copy of windows is invalid*
so i have had this pc, and this copy of windows for about 2 years now. ever since i was mailed my windows 7 upgrade disk.
2 months ago i ran into a nasty virus that forced me to reinstall windows just to put everything back to system default. i do not believe it is caused by the same virus, because this error is nothing like the type of attack the other virus used.
roughly 17 hours ago i went to work and left my pc on and running while i was gone*i do this a lot*. when i got home my background image was gone, and i was left with a message on the bottom right of my screen that told me my copy of windows was invalid.
i use malwarebytes, and microsoft security essentials. microsoft security essentials wont let me update because of the validation error.
i am also unsure as to how i can find my product key since my copy of windows 7 came from and upgrade disk*i do still have that disk somewhere, so if i have to blast the machine again i can although thats the last thing ill do*.
any help would be greatly appreciated.
