I was prompted (As normal) to install the latest security updates, KB3000850 & KB3011780.
After the reboot my PC was pretty much unresponsive, loads of apps not opening system hung on restart.
Booted up in Safe Mode and all is ok.
I tried a few things and came to the conclusion it was Avast, so I uninstalled it.
After the reboot it worked fine.
Tested uninstalling it and re-installing it.
Basically when installed I have problems, uninstalling Avast and all is ok.
The 2 updates where:
Security Update for Windows 8.1 (KB3011780) 1MB
Update for Windows 8.1 for x64-based Systems (KB3000850) 711MB
Both released 17.11.2014
Any ideas why these updates are causing me these problems?
Same here, on 2 different PCs.
Some apps do not start / take forever, including many Control Panel items (admin cmd, device manager, uninstall software etc.)
And most notably the System will not shut down. It just displays shutting down and loops forever.
Using avast cleaner to remove avast fixed everything, reinstalling it reintroduced the same problems.
I had one update today that I installed, (KB3011780), no problems so far. Seeing that I am not running Avast maybe Avast has a problem with this update.
Reading all posts above. The problem ocurred with kb 3000850 which, it seems, was an optional update. I can not say much about it since I do not run Win 8.1. I am just confirming that there is another Avast user in a similar situation after installing the same KB.
Was about to install KB3000850 too. Anyone tried to do a system restore and see if the problem still occurs? Windows should automatically create a safe state before installing updates.
Wow, hard to tell…seems others having install issues with this on the web…not necessarily Avast.
However, here is what happened tonight for me…have five home PCs…all W7 64bit, latest everything, KB3011780 pops up on them.
So on one PC I still have Avast 9.0.2021 I hit install on the KB…it installed and asked for reboot…which I then got the “Do Not Turn Off PC Windows is Configuring”…sat there for an hour !!! So…I did HARD reset with power button and reboot…asked me for boot options and I chose Normal Startup…Windows Logo and then message on registry updates happening…took five minutes…then to login screen…which had black screen prior for 2-3 minutes…and after login took 3-5 minutes to settle…all this on a very fast machine. Did a reboot and all seems OK…Avast 9 stable…all programs seem to run (Office, IE11, Firefox, some other utils I tried, etc.).
So, did same thing above to another PC with Avast 2015/2028 and same “hang” scenario as above…luckily stable now.
So, on 3rd machine I uninstalled Avast 9 and Avast cleaner then did MS update.
Not only did it not hang the install (config) took only few minutes then reboot.
Just to repeat the problem update is optional update KB3000850 exclusively for Windows 8.1 machines. Not the critical security update KB3011780 which is for every Windows.
OK…first, I apologize if I slightly hijacked the thread since I was talking about KB3011780…however, misread and thought you had issues there too. However, perhaps my solution can help on your other KB concern.
Today I did two more PC updates…same type laptops (DELL) with W7 64bit both MBAM Pro, CryptoPrevent and Avast.
One had V9/2014 & one V10/2015.
On BOTH I disabled (not uninstall) the MBAM & Avast shields…I also went into Avast UI and disabled the Self Defense Module. I then disconnected Wifi from Internet and did the KB3011780 update (had downloaded prior so only install needed) and it installed very quickly, on re-reboot shutdown it configed in under minute, on reboot Windows finished config under a minute and system was VERY responsive/quick. I re-enabled all shields and SDM. All seems well.
I can also confirm here:
three PCs with Win 8.1 x64 running fine with KB3011780,
but all three won’t shut down with KB3000850 anymore.
I also experience issus with some other processes as well.
I had same issue,uninstalling Avast and rebooting fixed ALL issues,ie no longer waits and waits at restart or shutdown,no lag or weird freezes,I tried Win8.1 with its Defender and no issues after,then decided to install Panda free version and again no issues,so seems related to those Windows updates last night and Avast.
So the solution for me was to uninstall Avast and either use Defender in Windows 8.1 or Panda free.
With fully updated Avast 2015 on task and a perfectly functioning system, I updated my test Windows 8.1 x64 Enterprise VM, including optional update KB3002340 (which is huge, and probably can be considered Windows 8.1.2) and it ended up completely borked, with an inability to search for things, broken menus, and popup messages like these attached. Worst of all, I couldn’t complete a reboot.
A full removal with the AvastClear tool cleared up the problem.
Per others in this thread, apparently attempts to reinstall the latest version return the system to a borked state, so I guess it’s goodbye to Avast for the time being.
kb 3000850 is a rollup of Win 8.1 and since last Win 8.1 rollup, called also Spk 1, brought so many troubles, Microsoft decided to make this one optional.
This November update rollup also includes all previous updates since our last image update in April 2014. This is a convenient single step to bring Windows clients and servers up to date. Unlike our April update, the November update rollup is not required to be able to continue to receive security or other updates.
There is something it does not like Avast or it should be installed without Avast and then install Avast : but some Win8.1 and Avast users are found it to be troublesome
