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

Install attempt fails with error 0x800f0922 whether I run Windows Update  to install this update or run windows10.0-kb4532695-x64_a85fd28af075ebfd8b0753d2c2aca244e926c3ce.msu

Running WIndows 10 Pro Ver. 1909 build 18363.592

I have tried every suggestion by HiltonOishi in https://answers.microsoft.com/en-us/windows/forum/all/failed-install-attempt-error-code-0x800f0922/c5eb31d7-f04f-4ff8-9d6f-f39e4f03944b

After the update installs I restart the computer and when it reboots it gets to 93% in "Working on Updates" then I get "We couldn't complete the updates Undoing changes"

Windows Update says this is an optional update. Should I just ignore the problem till the next update?

    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.

    Diskpart Shows:

    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

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

         >list disk 

         >select disk 0 [or other number]

         >list partition

    1. select the EFI partition

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

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

         >detail partition

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

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

    1. Exit diskpart
    2. Restart machine, install updates.

    "- So should I change it to Volume1? Is there any risk or this is an easy to proceed thingy? I honestly dont know how its allocated Volume4, since i didnt change nothing once received my laptop (only once i did a factory reset)."

    I just don't know what's up with that. Looking at your Disk Management,..

    Image

    I'd expect HarddiskVolume1 would already be there in the BCD. That is because I think it counts the partitions beginning with those on Disk 0 & progressing to the others. I can't think of how it could be saying ...4. Even if BIOS were set to boot directly to Disk 0 (instead of to the Windows boot manager), I'd still expect it be ...1.

    The only exception I think I know is, if there were an OS on Disk 1 & BIOS were set to boot directly to it. then maybe it would start counting with the partitions on Disk 1. But still I can't see how that would come up with a ...4 looking at the partitions you've got, Big puzzle to me how you're getting a ...4.

    Another thing is, I think that value (HarddiskVolume) might be set by Windows during/after the boot. IOW, it may not matter what is in there to begin the boot. It is set afterward to say which system partition was used to accomplish the boot. But really there should be only one system partition, which normally is EFI. If this is true, changing it yourself has no real effect anyway, It may act as just a suggestion to tell Windows where to start looking, I don't really know.

    Maybe, then, your BCD isn't being used at all & it just remains a ...4 from its last use (when presumably there actually was an EFI where it says). But how are you booting now then? Big puzzle. Did you look in BIOS Setup to see what's going on at the Boot page...?...

    https://www.sysnative.com/forums/threads/get-access-to-bios-settings-boot-menu-f-keys-hotkeys-by-system-manufacturer-oem.23010/

    Get access to BIOS settings & Boot Menu: F-keys/Hotkeys by System Manufacturer (OEM)

    Note: That should say what PF key gets to your BIOS Setup, but I know nothing (bad or good) of any links or downloads that are there (or anywhere else).

    (2) "- Im not able to view EFI folder, im not sure even if its existing, is it hidden or something ? Any steps to check this ?"

    Let's see all of this at an Administrator Command Prompt...

    DiskPart                    <<<Enter DiskPart

    Select  Disk  1           <<<Focus on Disk 1

    List  Part                    <<<Maybe there's a hidden partition on it (like MSR is hidden)

    Select  Disk  0           <<<Focus on Disk 0

    Select  Part  4            <<<Focus on partition 4

    Detail  Part               <<<I think we won't see EFI's type because Disk Management doesn't say EFI for it

    Select  Part  1           <<<Focus on partition 1 (EFI)

    Assign  Letter=S       <<<Give EFI the letter S

    Exit                            <<<Exit DiskPart

    DIR   D:\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI  /a       <<<I think the file won't be there

    DIR   S:\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI  /a       <<<I think it will be here

    DIR   C:\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI  /a       <<<Check C:\ too

    DiskPart                         <<<Enter DiskPart

    Select  Vol=S                 <<<Select the EFI partition by its letter

    Remove  Letter=S         <<<Remove the letter

    Exit                                <<<Exit DiskPart

    Use Ctrl-A & Ctrl-C to copy, then show us. With "/a", the Command Prompt can see what File Explorer may not see. If it says there is no BOOTMGFW.EFI there, then Windows can't possibly be booting from D: partition.

    (3) "- Yes, this is my factory reset partition. Windows come along with 1903 version. But in Oct 2020 i did a factory reset and my windows updated up to 1909 version. Below is history per updates."

    The upgrade to 1909 messed up the ability to do another factory reset. That partition is being used now to hold Windows' recovery environment which really only needs the 900 MB of partition 5. We should switch to partition 5 for that. Then repurpose partition 6 to be a data partition or give its 16 GB to C: partition. After that, make your own system image(s) of 1909 onto external media.

    Hi,

    Kind thanks for your help. Below is my comments as required.

    Windows Boot Manager


    identifier      {bootmgr}

    device          partition=\Device\HarddiskVolume4         <-- Should it be replaced with EFI

                                                                                                  allocated disk Volume1?

    "

    I would expect it should say HarddiskVolume1 just as you suspect. That is your EFI partition going by its type in the Detail Disk you showed...

    • So should I change it to Volume1? Is there any risk or this is an easy to proceed thingy? I honestly dont know how its allocated Volume4, since i didnt change nothing once received my laptop (only once i did a factory reset).

    Let's see a Detail Part on partition 4 (which is your D:drive)...

    DiskPart

    Select  Disk  0

    Select  Part  4

    Detail  Part

    Exit

    DIR   D:\EFI\MICROSOFT\BOOT\BOOTMGFW.EFI  /a        <<<And is the file there?

    (a) It should normally be a basic data partition:  ebd0a0a2-b9e5-4433-87c0-68b6b72699c7

    (b) And normally that folder & file shouldn't be on it. It should be on EFI.

    (c) Are you booting to the Windows Boot Manager in BIOS Setup?

    • Im not able to view EFI folder, im not sure even if its existing, is it hidden or something ? Any steps to check this ?

    (3) Your ReagentC /Info indicates partition 6 is the Recovery partition...

        Windows RE location:       \?\GLOBALROOT\device\harddisk0\partition6\Recovery\WindowsRE

    Judging from its size of 16 GB, it is a factory reset partition. So, a Reset would return the computer to its factory condition whatever that OS may be. If the computer came with Win 8.1, for instance, you'll end up back there. That could get messed up by doing an upgrade.

    Have you upgraded the OS since purchase of the computer? Or did it come with 1909?

    • Yes, this is my factory reset partition. Windows come along with 1903 version. But in Oct 2020 i did a factory reset and my windows updated up to 1909 version. Below is history per updates.
