If your "Windows XP" is "OEM" , you might have trouble once the OEM version is activated on a PC, it can never be legally transferred from it to another PC, even if the PC dies,That's why it is cheaper. I replaced the m/b on a PC then reloaded XP OEM but i could not activate it , rang Microsoft support they just said it was a different PC
& did not want to know about it, i ended up using modified version of XP. Thats the last time i will pay for anything from Microsoft.
