Cumulative update December 2020 - KB4592438 Failed to install

Hi All,

same problem with KB4592438 but with Error 0x80070002 ,   coming from  version 19042.630 ,  several attempts with DISM and SFC  but no success, nor offline KB4592438 installation. WU stopped working

After reading a lot on the web I tried this metod here found on this link

Error 0x80070002 - Windows Update - Microsoft Community:

Open administrative Command Prompt and type following commands one-by-one followed by Enter key.

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Close Command Prompt and see if Windows Updates works then

The two ren commands did not work for me since the paths were not found on my machine so I skipped them

After closing the command prompt I relaunched the Windows Updates procedure, KB4592438 was downloaded. Did a restart and at the end the update was successfully installed, now I am with 19042.685.

Hope it can help

French user so sorry for my english spoken.

Same problem with my windows 20H2

MSI X470 R5 3600 Nvidia 1060 3Go

All drivers up to date (even bios)

Tried all methods given on the net, also tried the software Reset Windows Update Tolls which seems to be good to solve update problems.

Tried to uninstall severals programs (Vmware or Cyberghost) but still no way .

Failed again with the stand alone update : download 100% installing 100% and.... Fail!

All updates before (during 2 years ) were fines but this is the first one wihch is problematic.

Update micosoft antivirus today via Windows update was fine too.

I had tried DISM and SFC, standalones to no effect.

What worked was uninstalling the 20H2 enablement (KB4562830) and then using the 20H2 MCT and doing the in-place upgrade.

19042.685 installed.

I also have the same problem if microsoft cant get it right then please leave it alone. these updates are stopping my work day in day out. i don't want anymore updates i will now be getting apple .

Hello,

I've had problems with this update as well. I've tried enabling .NET in Windows features, disabling firewall, clearing Software distribution folder and one other in System32, those didn't help me.

After that I did the mentioned:

sfc /scannow

dism /online /cleanup-image /restorehealth

and added

chkdsk /r

But what most likely helped me was "freeing" disk space. When I was googling for possible issues for this update I've found this thread and some general info that, among others, having not enough disk space might be an issue. I've had plenty so I have ignored that at first, but after a while I have recalled I'm using 4GB RAMdisk and my both Windows TEMPs are redirected to it. My RAMdisk starts with the system and in this case, update was quite big and 2nd part of the update was running after restart, so probably before RAMdisk could start or RAMdisk was too small for this update. I've changed paths for my TEMPs in environment variables (variables TEMP and TMP) to an existing folder on the system drive and it was last thing before a succeeded update attempt.

Since I wasn't making update attempts in between those 4 last mentioned steps I can't say for sure what combination of them helped, but I have a vague memory I've had a quite similar issue few years ago and back then it was due to update being unable to get to TEMP locations due to changed paths - not having enough available space and might have been just the same now.

A tip for MS crew: if the update needs disk space, let it create a folder in Windows folder for its own and delete it after the update is done as last part of the installation, that would make the update independent of TEMPs paths that can be changed to a disk too small or unavailable during boot up.

If it doesn't help you, focus on the error code for solutions connected to the error code instead of solutions to problems connected with the update number. Update is new, most error codes are much older, so it's very likely there's more to find looking for error code.
