Hi all I needed to know.. whether... I could modify a X64 VL SP2 disc... to use a x86 VL key I have a valid key for the XP Pro x86...but need to use it for a X64 pc. I have looked at the forum.. but can't see anywhere that answers these questions.... Can the same key be used? Can the Iso be altered to allow the X64 key? Does the EULA conflict...so altering will get the end goal? Can M$ pick up the difference with its Genuine checks..? Thanks all.. Spreng
