Major issues with KB3000850

This update broke my Samsung tablet.  I do not have Avast only Microsoft Defender.

The update successfully installed and asked to reboot.  I rebooted and the computer did the installing updates to 100% and then started a 'reboot'  at that time the computer never came back.

I let it run for about 10minutes and then stopped it.  Tried a few time to boot it up -- it did not boot.

I brought it up in restore/limp mode (pwer + volume up).  I cannot refresh -- 'drive locked'.  I cannot reimage -- says partition is missing.  However, if I go to the command Prompt, the C drive is there and chkdsk shows no errors.

Microsoft really messed this one.  Very similar to the April 2014 Rollup problems:

You would have thought they would have tested it better.

Not Necessarily An Isolated Avast Issue!

Although, my scenario doesn't have the impact on the system that some others are experiencing. My Windows 8.1 build has Windows Defender installed. I don't think it is a security program issue. The "optional" KB3000850 update of about 724MB, takes a long while to download and install on my usually speedy PC. After the process it requires a restart of course with a warning to not shut off the PC. Each time, when the process advances to 8% completion, my system attempts to reboot about four times. When the Login screen finally appears, I enter my password and it again prompts me to be patient as the system is configured. After a few minutes a message is displayed that the update could not be completed and the changes to the system are being reverted. So my environment isn't being damaged, but I can neither install this KB3000850 update, nor get rid of it.

I have a custom build:

ASUS Deluxe Dual

Intel i7 - 4770K 3.50Ghz

Windows 8.1 Pro - 64Bit

32GB

NVIDIA GeForce GTX 650 Ti Boost

Samsung 840 SSD 128Gb

WD VelociRaptor  1 Tb

I have been experiencing some issues my self... It takes loads of time for Windows 8.1 to completely load (it used to be very fast) and it doesn't shutdown.

Avast does not startup and does not uninstall. I get a program error and questioned if I want to remove Avast from the list of programs, even if I'm completely sure it still exists (and in fact is now running).

I tried unninstalling the update but couldn't, so windows reinstalled it...

Just to update... I tried system restore twice and twice the system restore didn't finish... Now I can't acesse control panel, system, programs and features..nothing.

EDIT: OK system and program features now load, but take ages... When undoing system restore, I can't get past a "Restarting" screen and am forced to force shutdown and the restart....

Way to go Microsoft!

You can restore via a recovery drive.  Alternatively, manually hit the "reset" button when you see the little loading bubble for Windows.  After you do this twice Windows should boot you into a recovery menu.  Once this happens, go to "Advanced," then "Other Options," and hit "System Restore."  This was the only way I managed to salvage my system from catastrophic failure.

I've got 3 computers with W8.1. 2 indentical DELL M4700 and 1 Intel NUC. None of the computers has AVAST or any other third parity antivirus installed. Using Windows Defender included i W8.1. My NUC installed the update just fine and everything seams to work. My first M4700 never started downloading the update. Maybe because I used it at the same time. I left that computer not installing. Thought of getting it a go the day after. I guess that's not going to happen. My second M4700 installed teh update end rebooted. Didn't notice any strange behavior. The problem begun when I tried to start programs. vmware Workstation didn't start. All Portable Apps didn't start. IE started and worked in "Metro mode" but as soon as I tried to switch to Desktop View it freezes the crashes. I was lucky and was able to rescue my computer by using a restore point.

Well I see this update has broken Avast AV but it has fixed a one year old Windows Explorer RAM issue for Webroot SecureAnywhere when Win 8.1 x64 first came out see here: https://community.webroot.com/t5/Webroot-SecureAnywhere-Antivirus/Explorer-exe-using-up-to-300mb-RAM/td-p/60523 and after KB3000850: https://community.webroot.com/t5/Webroot-SecureAnywhere-Antivirus/Explorer-exe-using-up-to-300mb-RAM/m-p/173343#M10637

I used the microsoft guidance by doing the following, go to programs and features, select windows updates in the uninstall section, find KB3000850 and select uninstall. The system will ask to reboot. Select reboot and wait about 5 minutes, then hard shut down and restart, the pc will configure updates and then you can log on to your windows account. This worked for me, I can now have the system shut down and restart like normal again.

The microsoft article said not to use the system restore feature for this specific update but to use the uninstaller instead.

The computer may crash if you restore the system to a restore point that was created before update rollup 3000850 was installed

Notes

• This problem applies only to Windows 8.1 editions.
• An installation of a Windows update typically creates a restore point to which the system can be rolled back in case the installation or the updates causes any problems. In this case, the computer may experience startup failures if you try to roll back the system to a restore point that was created before you installed update rollup 3000850.
• If the computer has Windows Recovery Environment (WRE) configured, the system automatically restores itself to the last-known working state.

Workaround
To work around this problem, use the Programs and Features item in Control Panel instead of System Restore. To do this, click View installed updates in the navigation panel in Programs and Features, select KB3000850 in the list, and then click Uninstall.

I experienced a different problem after installing KB3000850. I could no longer open RDS Published applications. 

When I logged in on Remote Desktop Services Web Access, I could start the published applications but it suddenly gave me a second login prompt. After I re-entered my credentials, it kept saying 'starting' and the window eventually disappeared.

I've tried this on different RDS environments I administer for different customers; same issue on each one of them, so it was definitely a problem with my Windows 8.1 client.

I also tested on a second Windows 8.1 machine with update 3000850 installed. Same issue.

Windows 7 client, no issues.

I remove update 3000850 using programs and Features and after rebooting, I could use the RDS Published Apps once again.

I don't use Avast, so this RDS Published App issue has nothing to do with Avast, but just with KB3000850.

Should I post this as a new thread?

I have the exact same problem. I also have 2 machines where the update will NOT uninstall for nothing and two others I uninstalled it from and of those 2, 1 works and the other is getting a MS Licensing protocol error when trying to start the remote app.

HELP MICROSOFT!!

REPOSTING...

KB3000850 is an Optional, non-security update. Feel free to hide it & move on with your life.

I also had issues with this update (KB3000850) after installing it the monitor on my Dell Alienware M17x R3 stopped working.

I attached a external monitor and powered off / on then i cloud use the external monitor to try to reinstall nvidia drives, but the only thing that worked was removing update KB3000850 since it was the only update installed yestoday is was easy to find.

Hopefully Microsoft makes a fix for the update.
