Windows 10: KB4343909 (OS Build 17134.228) failure = crashed MBR

Setup:
HP Compaq 8200 Elite Convertible minitower
Intel(R) Core (TM) i5-2500 CPU @3.30GHz
16gb RAM
64-bit windows 10 pro

Problem:
Windows 10 automatic updates have been trying to install update "2018-08 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4343909)". Once the pc restarts it begins to install it. after 20-40 minutes the update fails and attempts to restore the save point. at which point the restore will fail causing the pc to restart and enter a nice Blue screen screen with a frowny face and a barcode. Then it will restart.
Normally these updates install at 6pm once I am gone for the day. So these restarts will occur all night long till I return in the morning. At which point the screen is black with a white line blinking.

Fixing the PC after a crash:
Attempts at a system restore fails. The only thing that works is repairing the MBR using a windows 10 installer disk. I ran across an old post that, following the directions correctly, would fix the MBR and let the pc boot back into normal state. https://answers.microsoft.com/en-us/...c-81e572d546df Here is the link for that

At this point I have the updates stalled. I tried installing it from Microsoft directly without the use of windows 10 update to which it did not work.

Please help

:)

I think I'll enrich this thread, without being rude. . . . *Tongue

Listen to this. . . ! . *Cool
Good, . ?

OK, back on track. . .

This one was fast, maybe ten, or a bit more, minutes, including the restarts . . *really





Getting better every time, right. . . .*Biggrin






One question, though. . . anyone know what this was supposed to do ?

Weird...I've clean installed v.1803 two days before. First day, I received KB4343909 with no problems at all. Next day, checking for updates, KB4343909 was received/installed again but this time in a few minutes (5', restart included)




After second installation, COM errors stopped but a new error came up (repeatedly):



When I "Check for updates" it says that's "up to date" and everything goes on...perfectly(?) *Smile
