My system crashed and had my computer repaired by an it business. They restored my system and added microsoft xp. I recently started recieving notice from microsoft that the xp copy I am using is not legal. I have tried contacting the place where to work was done and they are now out of business. I was wondering if the license is saved by microsoft and can I get a copy of do it or do I need to purchase the xp program. I am looking for the license number of the xp that was originally installed on the computer when I bought it. Is this at all possible?
