[SOLVED] Windows 10 x64 KB4495667 update reaches 92% and then rolls back

writhziden · May 10, 2019

I always feel weird asking for help publicly as an admin, but hopefully it will serve as an example that even those of us who can generally handle our own troubleshooting still have to ask for help with areas outside our expertise.

The scenario I am facing:

The update downloads and installs to the point where a restart is required.
The update reaches 30% before the restart
The update reaches 92% after the restart
Windows stops the update and displays the message dialog: We couldn't complete the updates; Undoing changes; Don't turn off your computer
The error code given in Windows Update after it fails is 0x80070020

I tried several of the usual update fixes, but I've restored my system image to before those were tried to provide the person helping me here with a clean slate. Notable steps that did not work:

Clean Boot
Windows Update and BITS Troubleshooting through the built in Windows 10 Troubleshooting
sfc /scannow found no integrity violations
Dism RestoreHealth completed successfully but did not fix the issue
SFCFix also did not detect any corruptions

P.S. I would be interested in learning how to fix these issues, both for myself and for others on these forums, once this thread completes.

Hi!

I'll have a look at this for you :)

Please give me a moment to go over the log.

This indicates one of the following usually:

a) There is either a linux loader present (dual-boot system)
b) There is no free space on your System Reserved partition
c) There is security software interference.

a) Windows is the only OS installed, but the partition layout changed slightly. The boot partition was originally at the end of the table, so I moved the Windows partition slightly to the right and copied the boot partition before it. Windows boots without issues, but could the partition layout change cause problems with updates installing?

b) System Reserved has 142 MB available

c) Malwarebytes aggressively installed the active monitoring trial version (I miss the opt out option we used to have for the free version; any tricks for that?). I will remove Malwarebytes and try to install the update again while I wait for your thoughts on a)

Sysnative Windows Update · May 10, 2019

a) I have never seen that happen in practice, but that may be the case if the changes were made just prior to the error occurring as the Boot part is being referenced.

b) Could you please expand it to cca 500 MBs?

c) That option is still around - Deactivate Malwarebytes Premium Trial on Window... | Official Malwarebytes Support

Please try disabling Windows Defender as well. We had an issue with it once.

If that doesn't help, I'd like to see:

a) CBS.log
b) C:\Windows\Inf\setupapi.dev.log
c) Disk Management screenshot

Note: It would be wise to retry after each potential troubleshooting step, so we could determine what the real issue was.

Thanks.

I also forgot to mention the original drive was formatted as MBR and converted to GPT. I just noticed when looking at the boot partition that it is FAT32 while my other systems have EFI partitions for the 100 MB portion.

b) The overall size is 500 MB. I was saying that there are 142 MB free.

c) THANKS!!!! Note: Removing Malwarebytes did not resolve the update issue.

I am going to try rebuilding my boot partition and then try the update again. Then I will try your steps if I'm still having issues. Regardless, no need to reply to this post. I will post back with my status in a bit.

writhziden · May 10, 2019

Problem solved. It was a combination of converting my MBR layout to GPT and moving the System partition. Disk 0 contains my Windows installation. Partition 2 contains my C drive. Partition 3 is the problematic System partition that is used for the boot configuration.

Code:

Diskpart
list disk
select disk 0
list partition

My partition layout looked like:

Code:

Partition ###  Type         Size        Offset
---------------  -----------  ---------  ----------
Partition 1       Recovery    549 MB   1024 KB
Partition 3       Primary     100 MB    550 MB
Partition 2       Primary     463 GB    650 MB

It should look like:

Code:

Partition ###  Type         Size        Offset
---------------  -----------  ---------  ----------
Partition 1       Recovery   549 MB   1024 KB
Partition 3       System     100 MB    550 MB
Partition 2       Primary    463 GB    650 MB

EFI System partition:
c12a7328-f81f-11d2-ba4b-00a0c93ec93b

To make that happen:

Code:

select partition 3
SET ID=c12a7328-f81f-11d2-ba4b-00a0c93ec93b

Voila! Now the updates install again.
