I have just installed Windows XP Pro. The first thing I\ndid after connecting to the Internet was go to the\nWindows Update website.\n\nAfter scanning for updates, I tried to download and\ninstall Service Pack 1a. After the download was\ncomplete, it refused to install.\n\nI am logged on as Admin.\n\nI tried to install other update. ALL failed! Any ideas!\n\nAnd yes, I have already activated & registered my copy of\nWin Xp Pro.
