All the headlines are going to the big security fix in this month’s Patch Tuesday delivery for Windows.
I was intrigued to see four updates available that were targeted specifically at the Windows 8 Consumer Preview. The package didn’t include the Critical MS12-020 fix, which Microsoft says is available via Windows Update for anyone still running the Windows 8 Developer Preview. That suggests that the vulnerability is already fixed in the Consumer Preview code.
So what’s there?
This article introduces an update that improves the accuracy of the performance tracking data that is collected for the Windows Store on a computer that is running Windows 8 Consumer Preview. The performance tracking data helps us analyze and address potential performance issues. The tracking data is more accurate with this update. However, this issue does not affect the normal function of the Windows Store.

It’s encouraging to see bug fixes like this rolled out so quickly.

This is strange. Is 2680826 really in WU? The KB article makes it out to be a manually-installed hotfix. Yet, 2680826 is in my WU history from today. However, its description calls it a .Net 4.5 update. Either the description is wrong there or the number is.
After installing them, my Mail, People, Calender and Messagig apps refused to open. Just giving a error saying they simply can’t open. I wasn’t the only person with the problem.
George, there are updates for those apps available from the Store. I’m sure there’s a direct connection between the Windows and app updates. 😉
Any official word as to whether Windows 8 Consumer Preview or Windows 8 Developer Preview are affected, and if so, if there are patches available?
Liron,
Windows 8 Developer Preview has a patch, which is delivered through Windows Update. The Consumer Preview apparently is unaffected.
