I have a new laptop computer (Sager, Windows XP) and while online sometimes a "strange" unknown windows update process starts running. It shows a small icon in the system tray but doesn't say what it is downloading or how it was started. The only options is to "pause" and "start up again". I have checked for a setting that activates automatic updates, but can't find any. I have a network monitor utility that says it is coming from "origin2.download.windowsupdate.com". Any information on what this is and why it is running will be appreciated. If you need additional info please let me know.
