Reformatting

Hi. I have a genuine copy of Windows 7 and my computer has a lot of registry errors and my games which were working, have stopped working. And my computer is slow, though i have 4GB ram. I wanted to know can i reformat the whole PC and how to do that.

Hello,

Is your copy of Windows 7 a retail or OEM version?

Sorry for the very very very late reply XD (forgotten about this post) i have reformatted it on my own. Thanks for the reply anyways. :lol2:

Thanks for letting me know.
