Error 0x80070bc2 when Windows 10 update trying to install KB4048955 for version 1709

" The system spec screen shows 1709 with 1629.125 as the version."

Swan, that is where the incomplete Fall Creators Update has left me: at version 1709, build 1629.125. I'm unable to  restore my Mozilla Firefox or Thunderbird but the rest is working.

Ayres,

FWIW, I have a HP DeskPro 400 G1 MT purchased new in 2014. It has an Intel i3 4330 CPU, 16 gigs of RAM and an EVGA GEFORCE GTX 1050Ti GPU. It was problem free before the latest Upgrade arrived. The Fall Creators Update was disruptive and destructive and incomplete. It's taken two weeks to stabilize my partially upgraded system.

The next Windows 10 Update will be, "Windows Redstone" (as in the Redstone rocket?). Redstone will begin incorporating Linux. A Linux based OS will eventually replace Windows OS as it has already done at Apple. At that time I was an Apple user. Apple announced that OS 10 would not run on existing hardware, or, run current software. Every Apple user had to eventually and quickly buy new stuff which was very expensive. I came back to the less expensive alternative,  a Windows PC. Apple has a small user base and their products are rigidly controlled. MS Windows has a huge user base and the hardware & software encourage invention, innovation, non-conformity and diversity. If MS told it's customer base to buy new stuff, there would be lynchings in Redmond, WA.

So, I'll tough it out and cut 'em some slack. But unless MS puts me on the payroll, I'm on pause with further Updates of Windows 10. I'm not a beta tester.

Had the same problem with that AMD64 update on and Intel dual Pentium E6700.  I believe this system made by Acer back around 2010 has an AMD chip somewhere in the chipset on the motherboard, but it is not part of the main guts, it may be associated with the virtual USB based touch screen controller.  My machine is an early touch screen All-in-One.

@swansojb  Apparently my problem is/was a little different.  The Computer which was "hanging" on updates I was dealing with "hung" on a pair of updates.  The 1st one was the one released prior to the one that prompts this thread.  Both updates, no matter what process I went through, including all of your recommendations, was able to get a "completed install" on my system.  It is an "ancient" Acer Z3731-UR21P manufactured very shortly after Windows 7 (X64) was released.  It has an Intel dual-core Pentium E6700 and 4gb of RAM and an Intel Graphics chipset that uses an area in that RAM.

I ended up "chatting" with Microsoft Support and got a tech to link to me to check things out.  He ended up trashing a huge volume of "Log" files that had accumulated on the 1TB disk I had spinning.  He also performed the same rituals I had already tried twice.  In his final swath through the machine after he convinced himself that Microsoft Update on this machine had something "weird" going on, he disabled the history of updates on the machine, so my Check for Updates screen no longer displays any entries.  The system spec screen shows 1709 with 1629.125 as the version.

The available downloadable installers, at least in my case, did not "cure" the symptoms, but hopefully a subsequent release will bring back the update history and proceed onward. It was "current" as of about 1/24/2018.  The original install / reboot sequence was "working" by the updates apparently in my case "did not register" at the end of the reboot cycle in a way that the module that does the updating could see that the update was there!  I used a .DLL described in this thread from the console to pull a list of the installed updates and even though the display in "Settings" does not show them, THEY ARE ON THE SYSTEM
