I have a retail copy of Windows XP. I need to install this in my new computer. When I enter the key and do an online registration, will Microsoft have issues like "key already in use" etc. Do I need to ask Microsoft to deactivate the key so that there is no problem during the fresh installation. Can you please guide me on the tranfer procedure. Thanks. 1 person needs an answerI do too

As long as this copy of Windows is not installed on any other computer, you will have no problem in activating it. If the automatic activation fails because of the "key already in use" issue, choose the telephone option, wait for the human, and the human will activate Windows for you.MS-MVP - Elephant Boy Computers - Don't Panic!
