KB3205386 / KB3210721 We couldn't complete the updates, Undoing changes, Don't turn off your computer

Hi,



Sometime late last year (I can't remember when this started) I had a Windows Update that automatically installed and it resulted in an error. This has continued until now and I have been avoiding fixing due to time restrictions it but now must be
rectified. In my update history the failing updates are listed as KB3205386 and KB3210721. The problem occurs as follows:



1. Windows update installs the update and requires a restart - If I try to shut down the computer it will install the update and restart.

2. The restart configures the update up until 95-100% (not sure which number it stops at).

3. The screen then says "We couldn't complete the updates, Undoing changes, Don't turn off your computer"

Steps 2. and 3. take a long time, I haven't timed it precisely but I would estimate 2-3 hours.



I cannot shut down my computer without going through this process and the other day Windows scheduled the installation and I was not able to change the scheduled time.



I have read many forums trying to solve this and have conducted a number of processes to solve this problem:

• Viewed the Installed Updates and uninstalled both KB3205386 and KB3210721.
• Run Command Prompt as Administrator and entered:
  • net stop bits
  • net stop wuauserv
• Opened the Services console and Disabled and Stopped Windows Update
• Browsed to C:\Windows\SoftwareDistribution folder and deleted all the files and folders inside
• Downloaded the stand-alone package for both updates from the Microsoft Update Catalog website, saved into C:\updates
• Disabled my internet connection
• In msconfig (System Configuration) Services tab disabled all non-Microsoft services
• Restarted
• Run Command Prompt as Administrator and entered:
  • wusa.exe C:\updates\[updatefilename].msu
• Waited for installation, installation says it is finished and requires a restart.
• Click to Restart.
• Check the update history, it displays that the update failed.

At this point the same process occurs in steps 2. and 3. of the error listed at the beginning of this post.

I have tried KB3205386 first and then KB3210721. Neither have worked.

If anybody has suggestions where to go from here it would be highly appreciated.

 

KB3213986 failed to install 'undoing changes'

Having trouble with the latest update KB3213986. Tried all things suggested on many posts on this site but no luck. No matter what trying to install this update results in a restart that takes several hours to install then restarts to say it has failed and
undoing changes.

Here is my system summary: https://1drv.ms/t/s!As_TAcFgk3v7oysPrZZsmCuSqyDg

Tried everything I've seen advised bar re-installing windows again... Any help on this matter would be greatly appreciated
