I'm trying to update to the latest Win10 update released on 8/8/22. Ever since that update was downloaded the machine hangs
on the required reboot after the install. I have disabled updates until I can find a fix. I've tried to download the update and install
manually but get the same results. Other updates, such as .NET, download and installed fine. Once the machine hangs it has to be rebooted
2 times to get to the automatic roll back. At least that works for now. I've run the Update trouble shooter and it doesn't fix anything.
Windows Update and BITS services are both set to automatic.
There is an error in the event log but I think its from the install abort from a forced shutdown.
Installation Failure: Windows failed to install the following update with error 0x800F0845: 2022-08 Cumulative Update for Windows 10 Version 21H2 for x64-based Systems (KB5016616).
Update 10/5/22: KB-5017308, KB5017380, KB5018410 also FAIL in exactly the same manner as KB-5016616. Spinning dots on the reboot and the need to do a dual boot auto recovery. Title has been updated.
Any help would be appreciated.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
For me, the following solved the Problem:
Delete the Value data (all bytes) of
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\NL$KM\CurrVal(Default)
and
HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\NL$KM\OldVal(Default)
One reboot and CurrVal(Default) should be filled again.
If you are not domain-joined, i would not expect any problems.
I'm not giving directions on how to access and delete the value data because i want skilled people who know what they are doing to test my solution.
Same on my affected PCs -- no entries under HKEY_LOCAL_MACHINE\SECURITY
Did you run regedit with double elevated privs?

You are a genius. Following your solution, I installed all deferred updates including Windows 10, version 22H2. Thanks a lot.
It's not normally the case and most updates go in without any issues. It appears that MS introduced some major security changes around August and for some odd reason their updates failed to correctly install on many machines. Software bugs are not uncommon in updates and since this issue only impacted some machines, it appears that they are still struggling with a solution. A lot of times you fix something and break something else in the process. That is the nature of complex software code. No way around it and the users are the guinea pig. I am grateful that there are smart people on the forum who have the tenacity to troubleshoot and find the cause.
