Microsoft seems to have got off on the right foot in the new year – firstly, the release of the Windows 7 beta on Friday and then the first Patch Tuesday of 2009 with only one security update.

Tomorrow's patch is listed "critical" for Windows 2000, Windows XP and Windows Server 2003, but only "moderate" for Windows Vista and Windows Server 2008,
Microsoft's single security patch is in stark contrast to the Critical Patch Update that Oracle will issue on the same day which will update multiple Oracle products with 41 security fixes.
