A Friend of mine has a Computer. It came with a Illegal Windows XP. I have 2 Old Computers at home that I dont need any More. They have a Original Windows XP license. I have the License Sticker with the Product Key for both of them. Now I would like to know if my Friend could use one of the Keys to make here Windows Installisation Legal. How to I check if these Windows Product keys are not in use any more? 1 person needs an answerI do too

If Windows XP was installed on your old computer at the factory, it isn't possible to use its product key on a different computer. If you bought a retail version of Windows XP, you can remove Windows XP from your computer and install Windows XP on your friend's computer using your installation CD.Boulder Computer Maven Microsoft Most Valuable Professional
