Microsoft has advised users of Windows 7 (and Windows Server 2008) to uninstall a recent security update (KB2823324) after hundreds of complaints about computers not starting, refusing to re-boot, and other similar issues. Microsoft is blaming conflicts with 3rd party software for the errant behavior. Apparently, some Anti-Virus programs may also be affected, displaying symptoms such as issuing incorrect ‘Invalid License’ messages.
Microsoft is investigating behavior where systems may not recover from a restart, or applications cannot load, after security update 2823324 is applied. We recommend that customers uninstall this update. As an added precaution, Microsoft has removed the download links to the 2823324 update while we investigate.

Special Warning for Avast Free Users:
I am a perennial Avast Free user and the following is what happened to me after I installed this update: I went to my machine some time later and noticed that my Avast Free AV was displaying a “You are not fully protected” error message. Opened the Avast interface only to be greeted with… “Protection has expired – no changes or updates can be applied until renewal” (or something to that effect), along with a dialogue box requesting a current license key. Glanced up at the heading across the top of the interface and read…”Avast Free/Pro Antivirus“. What the… ??
My Avast Free had somehow been converted to the Pro version requiring a subscription to activate. I scratched my head… how could this possibly happen? I hadn’t installed any recent Avast program updates and inadvertently clicked the wrong button, had I? Most unlikely, and I certainly couldn’t recall doing so, but in the absence of any alternative explanation I downloaded the Avast removal tool, uninstalled the [now] Pro version, downloaded and re-installed the latest Free version… all good again.
Of course, I have since come across the reports concerning update KB2823324 which, as it turned out, is the obvious culprit and now uninstalled from my machine. If only I had known back at the beginning what I know now!
