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?

    I got the same error... after reading this thread I was like "Wow, Microsoft is doing it again".  The solutions here I gathered were two approaches: (1) repartition the HD and (2) reload Windows 10.  With all due respect.... Really?  I don't want to bring up the battle between MacOS and Windows OS here... but...updates on Mac has always been painless.  I guess I'll live w/o the update until Microsoft figures out a better way.

    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 others might benefit from my experience. The problem was solved but it was rather strange.

    I tried to install Windows from an ISO image created by the Windows media creation tool. It didn't work. Eventually I figured out it was not seeing enough free space for temporary files, but my C: drive has more than 500GB free.

    I went into DISKPART and after much rooting around discovered that the GUI ID for my EFI System partition was wrong. I'm guessing this happened when I expanded it to 500MB from 100MB as per  HiltonOishi's suggestion in https://answers.microsoft.com/en-us/windows/forum/all/failed-install-attempt-error-code-0x800f0922/c5eb31d7-f04f-4ff8-9d6f-f39e4f03944b.

    I set the EFI partition's GUID to c12a7328-f81f-11d2-ba4b-00a0c93ec93b as it should be and retried the Windows installation from ISO. This time it seemed it would continue, so I interrupted it and ran the update I had been trying to install, and it installed without a problem.

    I tried installing the update with the network disconnected. Same result.

    Thanks Jeffrey for your suggestion.

    It probably wasn't clear in my original post but I did try to download and install the update manually. It downloaded fine but the update doesn't continue installing, same as what happens when I use Windows Update.

    I am not running a third-party antivirus program.
