Win XP is reporting it is not a legal copy.
He runs his business and some proprietary software on this computer and we would like some way we can make Windows legal without a reinstall.
He is perfectly prepared to buy a legal copy. He did not pirate this software as he has an invoice stating his computer came with Windows XP Pro!!
Do we need to phone MS? Is there a way we can buy a copy from the store and do it without calling MS? He does not want to get the original seller in trouble even though the guy basically ripped him off.
