So that's pretty much everybody*.
Microsoft is planning a bumper patch Tuesday, with 13 bulletins that collectively fix 26 difference vulnerabilities.
Five of the bulletins are rated critical, seven as important, and one as moderate risk. Eleven of the baker's dozen of notices affect Windows, while two involve Office.
All versions of Windows will need patching, but Win XP and 2000 users (with five critical bulletins to consider) have more to worry them than Vista and Win 7 users (with each OS getting three critical updates).
As always, you get them here. You'll have to use Internet Explorer.

You can also set up Windows to automatically get new security updates:
* Windows 2000? Srlsy - who still uses that?
** A snarky Linux geek might recommend the Ubuntu LiveCD to get rid of malicious software. Snotty brat.
