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.
I blocked 5021233 but it still ran. 🤬
It won't let me roll back because its a reboot pending update.
Looks like i can only reset which will wipe out my software. 🤬
There is some fragment in the original update which for unknown reasons affects a tiny percentage of W10 worldwide installations. (200 PCs on this forum, max? Several billion worldwide?).
Part of a rolling set of updates required by MS, If not installed under one, will be rolled forward into the next routine update, (with by then other necessary stuff also) etc. So, not surprising at all. AND in the meantime you're missing other stuff necessary for PC security.
To cure it MS would need to know the detail issue. Clearly not our hardware, as proved by several us reinstalling successfully. So must be some odd, very rare, fragment of the affected PC's history, either update history or may be license history.
No chance.
Reinstall and enjoy your Christmas.
Your PC will also be healthier, faster etc with a clean install. But, yes it's a pain and needs very careful backups (using a new, and so faster, disc is a good safeguard, as per my previous). . But we can't change the world.
Just as a reminder the following summary is a way to defeat the update from being installed. The sequence is important.
You have to reset first without rebooting, then block, then check the block. Once an update is in the update path its stuck there. The reset removes that and allows you to block the update.
Links to download the 2 tools needed are elsewhere in this thread:
Note: Windows Update and BITS services must be running for this procedure
I wonder why there's not a log file anywhere that shows what's happening!
