Update Error 0x800706be for KB4103727

I am having a similar issue and also had the issue with the April Cummulative update that never installed.  Mine just says waiting for restart even though I have restarted my computer several times.  Just sits in the update section telling me I need to restart.

My computer is a home built desktop PC.

Processor AMD Ryzen 7 Eight Core Processor

Ram 16 GB 

Video NVidia Geforce GTX 1080 TI

I was able to use a bootable usb drive created with Windows 10 Media Creation Tool to break the failed install and get to the advanced troubleshooting menu. I was able to restore to previous version of windows which eas prior to Version 1803—the April update.  I successfully restored my system, then downloaded the April and May updates without any problems.

It's a Surface Pro 4, so obviously, you built it.  I have tried to install this update 4 times.  Each failed.

For me the update partially installed and then left the PC nearly unusable. Working on Sunday just fine, installed 3 updates Monday and 1 failed. Now useless box that reboots randomly depending on activity.

Example -Start menu no longer works, some Icons no longer work, message center only works though searching for specific items. Can only log off or restart using CTRL-ALT-Delete, SFC /Scannow completes to 30% or 41% then locks up and leaves no errors in log.

This is a new PC, an Intel NUC 7i5 with lots of storage (200GB free on C: ) 16GB RAM, on 500GB NVMe SSD.

I ran the security troubleshooter and it fixed some things so now update KB4103727 shows 100% downloaded and 100% installed, then errors.

Also ran check disk, ccleaner, reg errors fixed, virus scan, & disk cleanup. Basically this system is perfect except it will not install KB4103727 completely.

NEW UPDATE

I downloaded the update directly from MS Catalog and installed. Seems to complete ok and rebooted. But still shows in Updates. When I tell that to update it goes to 100% and says "Awaiting Restart" now I get a new error that says it can't.  So I restart manually but no change.

The good news is that now Icons and start menu now works, so something got fixed.

I have determined that I should use DISM to update the image and I can now see errors using SFC even though it stops at 48%.

I mounted install.wim on D:\test tried to use the restore health command. (see below) but it gets to 76% then say it cannot find the source. WHAT! Of course I specified the source.  Here is my command line options:

Dism /Mount-Image /ImageFile:D:\install.wim /index:1 /MountDir:D:\test\

To repair local Image:

Dism /Online /Cleanup-image /RestoreHealth /source:D:\test\windows /Limitaccess

MS KB is lacking: 

Any help with this is appreciated.

(I presume that is the image that needs mounting)
