Nothing bad will happen. It'll either verify or it won't.
I am trying to clean up my grandma's computer.
In the process, I want to update Windows XP to its latest version using Windows Update. I know that they check if it is a genuine version when you do updates.
The problem is, my grandmother has no idea wether it's legal. Some guy sold it to her, and I can't find the guy.
My question is, if I try to update Windows and it is indeed not original, will my computer lock itself? Or will it just prevent me from doing updates?
Or, is there another way to check if my windows is legal, before using the official Windows Update?
Thanks
