This coming Tuesday the 13th – second Tuesday of the month as usual – Microsoft is releasing 6 updates affecting the different operating system plus Microsoft Office. Two of the six updates don’t affect Windows XP, but only Windows Vista and 7, and the other four affect all supported operating systems.

Four of the six updates are classified as “critical”, Microsoft’s top severity rating. One is classified as “important”, the next severity down, and one as “moderate”. Three of the updates will require a restart of the computer to finish the updates, the other three may require a restart.

On related news, Adobe, the makers of software such as PDF reader, Flash, and others, has announced that it will, from now on, match their update schedule to Microsoft’s. So from next month on, expect Adobe updates at the same time as Microsoft’s – on the second Tuesday of every month.

Finally, Google has released Google Chrome 23.0.1271.64 for Windows, Macintosh, Linux, and Chrome Frame (a plug-in for Internet Explorer)  to address multiple vulnerabilities.
