Hi all, I've got a genuine copy of windows 7, I've had it a few years and the other day I got a popup ( from the toolbar not from a webpage) saying windows 7 needs activating. I have not made any hardware changes at all so this seems very unusual. In the past I have reformatted/reinstalled a couple of times but I've not done that for about a year or more.
I tried to activate it today but it just says my activation key cannot be used
Any ideas, seems strange to me.
