Microsoft today issued just one security update for Windows, the lowest
number on a Patch Tuesday since January 2009.
And for once, researchers urged users to spend their patching time dealing
with updates from Adobe, also expected today, rather than Microsoft's fix.
Today's update patches just one vulnerability, which is rated "critical,"
Microsoft's highest threat ranking, for Windows 2000, but is rated "low" for all
other versions of the operating system, up to and including the new Windows 7
and Windows Server 2008 R2.
