I had windows xp HOME on originally. There was a problem of a different nature. And the person who fixed it, installed Professional. Now i am getting a message, and having read up about it, i see where having pro in it's "counterfeit" state will only put my pc at risk.
I am in need of urgent help! I need to find out how to uninstall a counterfeit software (Windows XP PRO) and install that which came with the pc (Windows XP Home). Please, anyone, thanks.
