Update KB4056892 crashes with 0x800f0845

You make a great point. I wonder at what year or architecture they will cut off support.

I've had the same update problem with an old AMD Athlon x2 CPU. I've blocked the update for now using this tutorial Hide or Show Windows Updates in Windows 10

This processor is very old. I doubt Microsoft will ever do updates for this cpu and Windows 10. So be watchful for what updates you try.

It's hard to know what the real policy of Microsoft and others is when it comes to fixing bugs in old hardware and software.

For example, Windows 10 ran without any problems when first released on my 10 year old, 2GB machine (see My Computer specs for details). When Version 1607 was released, it introduced an unusual bug on my machine that caused it to reboot every 24 hours and 15 minutes. There was little information on the Web at the time about this problem, I guess it was not very widespread. It turned out to be caused by nVidia's Serial ATA Controller driver version 5.10.2600 dated 09 Aug 2007. At the time I could live with this by either shutting down every night, or rebooting the machine once per day at a time that suited me. Another work around was to replace the driver with a Microsoft generic driver, however this meant that the machine lost it's RAID capability, but it stopped it from rebooting itself every day.

When Windows 10 version 1703 was released, I did an upgrade install, and again all was well. The '24-hour reboot' bug was gone, and I found that the nVidia Serial ATA Controller driver was now at version 10.6.0.24 dated 06 Jan 2017! Someone had updated a 10 year old driver for 10 year old hardware to fix a bug when running Windows 10.

This new problem of old AMD Athlon machines refusing to boot with KB4056892 installed is much more serious, and affects many more machines, I think (hope?) a fix will appear shortly. I have uninstalled the update, and paused updates for the moment so my machine is running fine again.

Don't panic, just wait it out.

Sounds good Dave. I think we are like the beta testers for them. But i have my other Intel machines running fine with new Patch. One asus
ROG board I had to reinstall the AI3 Suite for fan control.
I found this thread at MS
After installation of KB4056892 boot failure, after roll-back error - Microsoft Community

Installed with Windows Updates on two of my machines , its mentioned as a cumulative update and chanced version to 192.
On my third PC it was not offered by Windows , so I downloaded the installer of this KB ,and it installed well.
Strange , its now called a "security-update " , and chanced version to 192 also.

I did not encounter any troubles , so far...........

Seems to be, amongst others, plenty of HP and particularly common Dell models still in use using the affected AMD chips that are still perfectly decent machines so I cannot really see how we can all just be abandoned by Microsoft, although the continuing silence doesn't seem good. Not even a comment in the update known faults list. I mentioned the manufacturers reconditioned models still on sale and many of these are advertised as Windows 10 and have the affected chips too. I guess we will find out the true impact tomorrow when people find their "work" computers no longer work.

Thanks for the link, I added myself to the list (232 and counting) of people with the same problem.

Dave.

i have same problem.....my CPU is AMD X2 4000 Now 10 years old but with m/b that was replaced in 2011, so after reading these posts wondering if I will have to get new cpu and maybe m/b if MS don't come up with anything. It's been running Fall update fine no probs till this darned update!! Now will pause updates but one can't run indefinitely like that. I guess the age of these chips are getting a bit old now! I

After my previous post, ive tried to pause updates, but when I go advanced options etc, there seems to be no Pause update toggle button! I'm on Fall Creators but toggle is not there! it has "Choose how updates are installed, Enabling policy, Delivery Optimisation, Privacy Settings. ....
please can someone advise?! thanks

The 'Pause Updates' option is not available on Windows 10 Home edition, it's only on Windows 10 Pro and (I think) Educational editions.

Have you tried Steve C's solution posted above?
