A friend of mine has XP Pro on her computer which has to be reinstalled, but unfortunately, has lost the disc which came with the computer. Her brother has a copy of Win 2000. Question is this. If she installs the Win 2000..........will she be able to use the Microsoft site for updates without them knowing. I`m sure this question has been asked before. I say it won`t matter....she`s scared to do it.
