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?

    Your type, attributes, & size on the EFI System partition look fine to me. I wouldn't increase its size. And it's just fine for it to be partition 2. Also, the other partitions look good. The reset seems to have done a good job with that. My Recovery partition is 790 MB compared to your 529 MB, but I think yours must be OK, if that's what the reset did.

    (1) What OS Build is at "START, Settings, System, About"...

    (2) What do you see at "START, Settings, Update & Security, Windows Update" -- is there a message or any activity going on?

    (3) The first thing to try is "START, Settings, Update & Security, Troubleshoot, Windows Update". But say a prayer first that it will actually do anything useful.

    (4) Let me see a BCDEDIT & a ReagentC /Info...

    (a) Type "CMD" into Search, & click "Run as administrator".

    (b) Enter...

    BCDEdit

    ReagentC  /Info

    Then use Ctrl-A & Ctrl-C to copy it, & paste it here. Here's mine...

    Hi,

    Having experienced exactly the same issue described in these posts and with a recently reset windows 10 installation. I was following the above and I have participation 2 set with the correct guid, is it possible the system partition is not sufficiently large? 

    DISKPART> select disk 2

    Disk 2 is now the selected disk.

    DISKPART> detail part

    There is no partition selected.

    Please select a partition and try again.

    DISKPART> list part

      Partition ###  Type              Size     Offset

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

      Partition 1    Recovery           529 MB  1024 KB

      Partition 2    System             100 MB   530 MB

      Partition 3    Reserved            16 MB   630 MB

      Partition 4    Primary            465 GB   646 MB

    DISKPART> select part 2

    Partition 2 is now the selected partition.

    DISKPART> detail part 2

    The arguments specified for this command are not valid.

    For more information on the command type: HELP DETAIL PARTITION

    DISKPART> detail part

    Partition 2

    Type    : c12a7328-f81f-11d2-ba4b-00a0c93ec93b

    Exactly the same problem on same version. Stops at 94%

    My Windows 10 is a recent download performed with the help of MS second level support on 20/02/20 when the previous Cumulative Update failed. 

    Will contact them again next week

    I still wonder whether the case is the same for CuongPN.

    BTW, I once messed with my EFI & had to restore its proper ID GUID afterward (& its attributes too, IIRC). But in the meantime an update never tried to enter (or so I don't recall), so I can't personally vouch it fixes  that. Also, I want to say it's never been necessary for me to increase EFI's size. In fact it used to be 100 MB but got down to 99 by messing with it. Still no update problem.

    PCR wrote "I don't know that it would be a cure, but you may as well check whether your EFI partition has the right ID GUID..."

    As you saw in my post on February 2, that was indeed the solution.
