Microsoft got big plans for everybody for next Tuesday, and I hope you haven't made any dinner plans because you will be busy patching (or working with your old friends like WSUS to get the patches tested and released).

A total of 17 Bulletins are going to be released according to Microsoft's pre-release. 9 bulletins are rated critical and 8 are rated important. It pretty much affects the usual suspects (Windows, Internet Explorer and Office) as well as some less regular guest starts like Microsoft's developer tools.

The critical patches apply pretty much to all versions of Windows (XP, Vista, Windows 7 and 2008) with one or two exceptions.
