Tech Support: Windows 10 Update with Error Code 0x800F0922 – EaseUS

My bet taking into account what this update does is on this scenario in your case:

1. Low System Reserved partition space

When there is not enough free space for the system reserved partition, the computer will not be able to load new Windows 10 installation files with an error code such as 0x800F0922.

Yes, I'd found this possible cause in my searching. I do not have a separate System Reserved partition - never have. I have 16GB free on my system partition, which ought to be plenty. I suppose I could try extending it and see what happens...

System Reserved Partition and OS Partition are two different things.

Yes, I know that, but you don't need to have a System Reserved partition - the functionality it contains can exist on the system (OS) partition. I've been running without a system reserved partition for many many years without issue.

[Actually, in a UEFI/GPT setup like mine, the Sytem Reserved partition functionality resides in the EFI system partition. On my system, it is only half full.]

This page doesn't mention Version 1909 and it's not being offered on Build 18363.628 which is now downloading Build 18363.657.
KB4524244 Security update for Windows 10 - February 11

EDIT: after some searching I found both editions on WU but they were well hidden in the list.

WU picked up the CU to Build 18363.657 on my system, but not the KB4524244 update, but the bld. 18363.657 update is a CU. I also notice that since updating to v.1903, WU runs every day right after boot up. It used to run randomly roughly every day, but long after boot up. Also, since the update to v.1903, the WU process is stopping Norton’s firewall and AV functions. After the restart W10 posts repeated messages that Norton, nor Defender, are not running. A click on the Norton desktop icon shows its functions are indeed running (Task Mgr. also verifies all is well) and the message center alerts go away.

Update: WU did an auto update on 02/13/2020 with KB4524244 sometime while the system was idle and I was away. And the message center again was reporting that there was no firewall, nor any AV running, and again Norton was indeed running and had just finished a quick scan of the system.

This looked like a 2 step process. IT never appeared yesterday, but when I powered the desk top this AM, there it was. I noticed on my other 2 systems, it required a restart to get the second KB (KB4524244).

Same here, un-paused the updates earlier today and got the whole lot installed.

One could even argue that this chappy has been deployed silently...!

i have credential guard enabled on my machine, not sure why having it enabled would require two restarts but no restarts for systems with credential guard turned off.

I have run windows both with and and without the reserved partition (assuming we are talking about the partition where the winRE files are stored). at one point I might have agreed with you about not needing the reserved partition. However, I have learned the error of my ways. the reserved partition, and the files there exist for cases when there is an error (with luck, a recoverable one) with the OS partition that won't even allow a windows safemode (or command line) boot. having the winre on a separate partition means you can still (possibly) recover your OS without resorting to a clean install or factory restore. I assume MS did this since you can not run windows setup repair with out having to actually be in a working copy of windows. back in the XP/9x days if you could not get windows to boot, you could drop to the command line and run setup to repair your windows install. you would just press the 'R' key once windows setup detected that you already had windows installed.

----UPDATE----

so the update installed, no errors as far as i can tell. windows did reboot twice because of activated credential guard, as far as i can tell, no differences in how windows boots, or in operation of windows it self

I have never needed the System Reserved Partition - I simply don't worry about it. If worse comes to worst, I just restore a recent Macrium image. My data is all on a separate partition anywy, and well backed up.

Can you explain in detail as it is always installed as a default and contains the WinRE environment. Check with >reagentc /info
In fact there are more than one System reserved Partition.

I have no WinRE environment. It is evidently not required.

Code:

C:\WINDOWS\system32>reagentc /info
Windows Recovery Environment (Windows RE) and system reset configuration
Information:

    Windows RE status:         Disabled
    Windows RE location:
    Boot Configuration Data (BCD) identifier: 15b0b32f-7b08-11e9-974d-aa0e89570925
    Recovery image location:
    Recovery image index:      0
    Custom image location:
    Custom image index:        0

REAGENTC.EXE: Operation Successful.

Not sure what you mean by 'In fact there are more than one System reserved Partition.' A quick look with any partition management software shows that there are not more than one system reserved partitions. In my case, there is not even one.
