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?

    Thank you for your suggestion but I think it is a little drastic for an update that Microsoft says is optional. I will wait for the next update and see.

    Thanks again for your help.

    I thought the same.

    Your EFI partition has lost its proper ID. Restore it this way at an Administrator Command Prompt...

    DiskPart                                                                                      <<<Start DiskPart

    Select  Disk  0                                                                             <<<Select drive 0

    Select  Part  1                                                                              <<<Select the EFI partition

    Detail  Part                                                                                  <<<Show improper ID

    Set ID=c12a7328-f81f-11d2-ba4b-00a0c93ec93b  Override     <<<Give it proper ID

    Detail  Part                                                                                  <<<Show proper ID

    Exit                                                                                              <<<Leave DiskPart

    Best reboot afterward to be sure it registers.

    That should do it. If it solves the problem, both helzayat & crackshot91 also deserve credit.

    Min has different Ltr, Label and Offsett in Bytes. Does this cause problem as I also have this nonstop updating and Undoing updates with the error code 0x800f0922?

    Everything looks fine with that, though partition 1 is probably empty & useless. It was replaced with partition 5 during an upgrade, as I'm sure your "ReagentC /Info" will show.

    (1) Your EFI partition has no letter -- which is the normal condition.

    (2) It also has no label which is OK. If you want one...

    DiskPart <<<Enter DiskPart

    Select  Disk  0<<<Presuming that was Disk 0 you showed

    Select  Part  2<<<Select your EFI partition

    Assign  Letter=S <<<Give it letter S

    Exit   <<<Exit DiskPart

    Label  S:  ESP                <<<Give EFI the label "ESP" (EFI System Partition)

    DiskPart<<<Enter DiskPart

    List  Vol <<<Should show the label "ESP" now (with the letter "S")

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

    Remove  Letter=S<<<Remove the letter S

    Exit<<<Exit DiskPart

    That is probably worthwhile to do, but it won't solve the current problem.

    (3) Let me see the rest of what you've got per what I posted to Smelltastic on page 2.
