Good heads-up. Thanks for posting.

They probably won't show up in Windows Update until tomorrow, that is what usually happens.

Bated breath holding.

Just installed the updates and my computer is just fine, Windows 7 Home Premium 64 bit

I just upgraded this one two months ago.

Booting up after the updates took 4 minutes and every time after that is taking 4 or 5 minutes. Used to take 40 seconds.

I have an SSD and I barely boot up in 45 seconds.

Nice avatar, Doc. Is that a PhotoShark?

@ kona and anyone else interested...

Not all updates complete their entire 'update process' immediately, so it is quite possible......and in cases like with .NET etc. (quite probable) that the 'updated' file(s) in question may still be performing other operations in the background including but not limited to cleanup etc. etc. etc.

The above can of course have an averse (albeit temporary) effect on system load-time(s) and/or program responsiveness etc. etc.

As stated for instance .NET updates sometimes require additional post-update processing/file operations and while those are usually scheduled for times when the CPU is idle, it is possible for some of those file operations to take place on subsequent system 'reboots' and/or at other times when they may be more noticeable to the user.

I have Windows 7. My point is that even after rebooting 5 times it's still taking upwards of five minutes to boot when it used to take one minute at the most.

If you are using Win8.1 with WB please do not install the optional update in the list until after you upgrade WB to the latest files which will be out on Wednesday.  The automatic ones should be fine, just avoid the optional one for now.

Opening the 'Computer Management' console snapin (START> RUN>compmgmt.msc) and parsing the 'Windows Logs' by drilling down in the 'Event Viewer' may help shed some light.  For explanation of individual event ID's there are several web resources readily available via a quick web search.
