Today is a big patch day for Windows users.  Microsoft released many patches, mostly critical, today.  If you have auto-update turned on, you probably have them downloaded and ready to install.  If not, Windows Update site is overloaded so it will take a while to get them.  If there aren't any updates, try again when the site is not so busy because network timeout seems to be interpreted optimistically by Windows Update scanner.  I installed 4 patches on Windows Server 2003 and 5 patches on XP.  On top of all that, I installed a script debugger patch from Office Update.  Damn those 17-inch PowerBooks are looking good today.
