I purchased a Dell from the Dell auction site a few years ago and it's now out of warranty. It came loaded with Windows XP Pro and recently got a virus. I had to format the machine and when reinstalling Windows XP Pro I found Dell put a Windows Media Center sticker on the machine so the key won't work. I ran a keyfinder program before I formatted and that key won't work either. I checked the system configuration on the Dell Website via Support Tag number and it shows the machine had WIndows XP Pro installed on it. Is there anyway to get the product key to reinstall the software on my machine without calling Tech Support and having to pay $50 for them to give me a key they should have given in the first place?
