Just a question for those who understand this shuff.

I have an xpreditor pgs b, a gaming computer, it runs windows XP, can I take it to the local computer shop [Thailand ] and can I up grade to a newer version of windows.

XP is fine for most things I need, but newer games won't play on it, locals will put anything you want on it for 200 Baht, not a legal copy of course.

So is there problems running illegal copies and what would be the best version for this computer.
Thank in advance for any advice.
