Ok thanks. My family's PC has XP as it came installed on the machine but they never got a disc with it for some reason unknown to us all (can't remeber now as it was a couple of years ago). I have XP on my machine as I bought a copy (disc) from a retailer. Can they use my disc to install XP on their machine again if they re-format the PC first? (which is what they're wanting to do, but they don't want to have to buy another copy of XP for £70 approx.)

I need to know how many times Windows XP Home Edition can be installed before Microsoft start asking questions. Also, is it possible to install it on two computers, from the same disk?

How many times can I install Windows XP Home Edition before Microsoft start asking questions?
