Update Failures.


Grrrr! Bloody Windows 10 again! (I have version 1709).
This time it’s “Quality Update” 2018-01 aka KB4056892.

2 newer AMD64 machines updated ok, but the 2 AMD Athlon 64’s hang up during the reboot.
Failure codes are 0x800f0845 and 0x80070643.

Apparently, this update is for Intel CPUs, so are nothing to do with AMDs at all.
It appears that in their wisdom, Microsoft tested the fix on Intels, but never thought to see what it would do to AMDs.
(Or possibly they only test things on the latest model of anything).

Anyway, looking online finds that a number of people are complaining about this, and someone has come up with a temporary workaround.
There is a little known Microsoft tool for hiding updates to be found at

To get there, you need to reboot the machine 3 times, (if necessary switching it off between times), which invokes a repair mode. It is supposed to either fix it, or roll back the update. One machine rolled back, the other didn’t, so It had to go back to the last restore point.

There is no sign of version 1709 on the support page, so I chose the version for “Anniversary Update” (1607)
You need to download the “Show or hide updates” troubleshooter, (which is called wushowhide.cab) and open it, which causes it ro auto-run.
Then you cand select hide updates, and it looks around a bit, and eventually comes up with a list, and you can check the box for “2018-01………..(KB4056892) and click next.
Check it says 2018-01……. is fixed with a green tick, close and restert windows.
Eventually an update check will show all is ok.

"Quality Update" indeed!
