I'm not going to debate the morality of "stealing" virtual content, even though im for it.
There should be NO difference beetween a copied version of Windows and a "genuine" one. Absolutely none.
I think ppl are mostly mad at u for "stealing" when they tell u otherwise. Its possible that he did not copy it correctly, but no one actually copies it today - we just use images and they are all well. If Windows Setup was missing files, it would not run well so u would know, but i doubt he installed this copy himself.
Could ur problem have to do with the OS? Yes, u may have viruses or spyware. This would mean that Windows isnt running well. You could also simply have a problem with the game, but without more info on the PC and the game, i cant help u.
