Error 0x800f0922 for 2020-01 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4532695)

I did that too and I still get the error message!

Your method unblocked me as well. I had recently used some third-party disk partition tool to move my EFI partition and I'm positive this caused the issue.

Some further instructions:

1. find your efi partition in disk manager [I find it's easiest to use this tool] or use diskpart or other tool
2. open cmd prompt elevated
3. Run diskpart

     >diskpart

3. You may need to dig a little to find the correct drive and partition...

     >list disk 

     >select disk 0 [or other number]

     >list partition

4. select the EFI partition

     >select partition 3 [only an example. Yours may be different]

5. Now that you have the EFI partition selected you can see details of the partition:

     >detail partition

6. Look at the Type. Is the GUID there different than c12a7328-f81f-11d2-ba4b-00a0c93ec93b?
7. Set the partition ID

     >set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b

8. Exit diskpart
9. Restart machine, install updates.

Hey. I have a problem like that. Diskpart shows me the Correct ID, and  BCDEdit + ReagentC doesn´t show wrong things. I also tried SetupDiag but it was shown nothing.

I am running out of options and dont know what to do now.

(1) You selected Disk 1 then listed its partitions...

DISKPART> list par

  Partition ###  Typ               Größe    Offset

  -------------  ----------------  -------  -------

  Partition 1    System             100 MB  1024 KB             <<<EFI

  Partition 2    Reserviert          16 MB   101 MB              <<<MSR

  Partition 3    Primär             203 GB   117 MB               <<<Windows

  Partition 5    Unbekannt           19 GB   203 GB             <<<Not a known partition type

* Partition 4    Wiederherstellun   521 MB   223 GB        <<<Recovery

(a) How does partition 4 come after 5? Were you doing partition work of some kind? You should do a reboot as soon as possible after partition work so that the full system knows of the changes. After a reboot, I'm hopeful 4 & 5 will be listed in the right order.

(b) Unbekannt means "unknown". Normally I'd want to say it was a factory reinstall partition. But those usually have the same partition type of a Recovery partition, i.e., Wiederherstellun. Have you altered its partition type?

(2) Your ReagentC shows...

WinRE-Status:      Enabled

WinRE-Ort:          \?\GLOBALROOT\device\harddisk0\partition4\Recovery\WindowsRE

Partition 4 is good, but it says "harddisk0". That's Disk 0. So I suspect you've got two complete installations of Windows plugged in at once, which is no good. Especially, you don't want two EFI partitions. Windows can be confused when it does a reboot as to which should be used.

(3) Your BCDEdit says EFI is on "HarddiskVolume1"...

Bezeichner           {bootmgr}

device                  partition=\Device\HarddiskVolume1             <<<Partition 1

path                    \EFI\MICROSOFT\BOOT\BOOTMGFW.EFI

HarddiskVolume1 means Partition 1, but which Disk is it referring to? I used to say it would be Disk 0, because it counts partitions starting from Disk 0. But now I think, if you booted directly from BIOS to Disk 1, it might start counting from there. Then, it's saying the EFI on Disk 1 was used to achieve the boot. Do you know if BIOS is set to boot directly to Disk 1?

(4) Show us a "right-click START, Disk Management". Use the separator lines in the header to make the columns readable. Use the separator line between the panes to scrunch it smaller, but show all the Disks.

(1)

(a) Yes i was once dooing partiton work. I dont exactly know what is was, but i had an error, where i was not able to boot so i did some partition work. I only know there was some kind of missing data in the EFI partition.

(b) It was a long time ago but it could be, that ive deletet this partiton.

(3) I will try with the next boot, to look from which disk it is booting.

(4)

Hope you can read it
