I had to completely reinstall Windows. I couldn't install XP Pro because I don't have the key. The disc was provided with my Dell Laptop, but no key. The key on the label was for Windows Vista (which I also had the disc for). I am restoring files from backups. When I tried to access a file I was told I didn't have permission to access that folder (Documents and Settings). I tried to change permissions, but was denied. I cannot figure out how to log on as the administrator. There is no Icon for it, and the Help is useless. I am the king of this computer. But I can't make it understand that. How do I get rid of this access restriction for the entire computer?
