Gadzooks! I almost fell out of my chair yesterday, when I checked Windows Update just after lunch, as is my usual wont on Patch Tuesdays. There were no less than seventeen (17!!) updates waiting for me to download onto my production machine, and as I worked my way through my notebook (I’m currently caring and feeding for 6 of them right at this moment, because my Dad and his D630 notebook are visiting right now, and I bought a D620 for him to take back to Virginia with him for my nephew, Collin) and four desktop PCs, the number of updates ranged from a high of 15 to a low of 12 for the rest of those other machines. Of course, one of those items is the standard Windows Malicious Software Removal Tool (October 2010/KB890830) so there is really one less actual security updates and patches involved in this latest batch.
For the complete details on this enormous batch of items, see the Microsoft Security Bulletin Summary for October 2010. For other interesting coverage, see Emil Protalinski’s October 2010 Patch Tuesday will come with the most bulletins ever at Ars Technica, and SoftPedia’s Patches Released for 49 Vulnerabilities in Windows, IE, Office, and .NET. Of the 16 actual security bulletins, 4 are rated Critical, 10 Important, and 2 Moderate. Looking over the mix of operating systems, platforms, frameworks, and applications involved, IT or security staff will want to look these over quickly, and get all of the Critical and at least some of the Important and perhaps even Moderate items into testing, and ultimately into deployment, with some dispatch. Windows 7 is now definitely into the mainstream with many more of the individual bulletins listing both 32- and 64-bit versions of Windows 7 among the affected platforms (only 4 of 13 show “not applicable” for those bulletins that target Windows OSes).
