I DID buy a genuine vista but after I installed Vista SP1(i don’t know what it is) my vista still pass the windows validation. But, when I right click at computer, the system shows that my vista is not activated yet. But, when i tried to activate it again, there is something wrong about the OEM stuff.(i also do not know what it is). So,how can i activate my vista again?
