An annoying feature of Microsoft Windows XP Service Pack 2. It automatically downloads "critical updates" to fix security holes found almost daily in Internet Explorer and in other parts of the operating system, then it harasses you to restart your computer. If you click "Restart Later" the box will pop back up in about five minutes.
noob: Automatic Updates rules!
h4x0r: Don't use it...if you do I won't be able to hack your PC! Liek, omg!
