After installation of KB4056892 boot failure, after roll-back error 0x800f0845

Different suggestions work for different machines.

I should have quoted the interesting part.

The poster offers a way to uninstall the offending update in a system already compromised.

If you can boot into your recovery environment and open a command prompt, you can follow its instruction starting from 3).

3)  At the command prompt - first determine what drive letter your boot volume is assigned.  On mine, it was E:.  It will likely be C: D: or E:.  You might find that do a c: - then doing dir - hitting enter or d: - dir - enter - will be easiest to figure out which drive it is.  You could also go into diskpart and look at the Volumes (diskpart (enter) - list volumes (enter) )

4)  Substitute the correct drive letter in each of these commands (where e:\ is your Windows volume)

dism /image:e:\ /get-packages

5)  After you run this command - it will show a list of packages.  Look for the most recently installed - it likely will say "Install Pending"

6)  Take that Package identity from those results and run the following command (where package name is the package you want to remove):

dism /image:e:\ /remove-package /packagename:Package_for_RollupFix~31bf385ad364e35~amd64~~15063.850.1.10

Thanks Valdemar_Klausenburg_III for the information about AMD's prospective updates and a bit of history on AMD's performance, or lack of in 2007.

Just as a bit of feedback  on the wushowhide.diagcab utility. It did not work for me as it saw other pending updates except KB4056892

I am going to stop all updates on my BU AMD system until some further resolution is developed. Not ideal but needs must.

Even after the updates reset, if the update somehow sneaks in, the best way would be to use the troubleshooter tool.

Yes, the update does download and install even after running the reset script, for me the reset only wiped out my update history and the history was not restored even after a successful System Restore.

I recommend using Windows Update Show / Hide (wushowhide.diagcab) to hide the update as this is the only solution that works for me.

I'm a little perplexed why the update still downloads and installs even though Microsoft says KB4056892 is ........... Microsoft has temporarily paused sending the following Windows operating system updates to this subset of older AMD processors:

Any thoughts on why my system keeps getting KB4056892 which prevents reboot???

Thanks,

While I have plenty of workstations to test this ((JoeReedy's post ->"But appears to not be a problem."), I am kinda busy recovering lost systems.  I saw 2 systems relocked yesterday, before updates could be stopped..

"To prevent this issue, Microsoft will temporarily pause Windows OS updates to devices with impacted AMD processors at this time."

That statement was released on the 8th, but systems were still being locked yesterday the 10th.

My approach is to wait for the resolution, if any will come.

In the meantime I have Hidden the update in the pc at risk.

Deactivating the Virtualization support in the BIOS, on some pc has permitted a normal boot.

After you have managed to successfully Hide the update, you can reactivate it.

I got this error on PC full of accountant softwares and certificates which meant I cant reinstall windows that easy. System restore was corrupted so that wasnt a solution.

Solution I did is that I took out HDD out of AMD pc and connected it on different Intel PC.

Booted up there without any issues removed/disabled updates and put back disk to AMD pc.

Worked perfect.

Thanks ZoranJonjic . Did not think of trying that but will if my saved image fails.

Thanks again
