I have a copy of Windows XP Professional Edition, and I wish to check its product key. I don't want to install it and then discover that it's not genuine! How can I do that, please?
There isn't any way to check the product key. Where did you purchase Windows XP Professional and are you suspect the copy may non-genuine? Please visit the How To Tell website located: http://www.microsoft.com/resources/howtotell/ . Maybe this will provide you with some assistance in assertaining if your copy is genuine or non-genuine.
