Windows 10: Cumulative update December 2020 - KB4592438 Failed to install

I am trying to install KB4592438 for Windows 10 20H2. The patch is downloaded without any issue. But the installation fails and the screen starts showing - Undoing changes Don't turn off your computer. The error message is - Some update files are missing or have problems. We'll try to download the update again later. Error code: 0x80070003.

Cumulative December update

I tried to download and install the December Cumulative Update from the website you had listed and did not have any luck. I received error messages stating that it would not install and it still has not come through windows update. Do you have any other
suggestions?

 

Windows 10 Cumulative Updates failing to install since April

Steps I have already taken to resolve the issue:

• Windows Update Troubleshooter: Did not find any issues;
  
• sfc/scannow: Windows Resource Protection: Did not find any integrity violations.
  
• DISM /Online /Cleanup-Image /RestoreHealth: The restore operation completed successfully.
  
• ‘In-place’ re-installation using Image Creation Tool or ISO file: Does not support Windows Enterprise.
  
• Re-installation using standalone Windows Installer MSU file (downloaded from Windows Update Catalogue): Installation failed.
  
• deleted all files from C:\WINDOWS\SoftwareDistribution\Download: It did not help.
  
• cleaned C:\WINDOWS\SoftwareDistribution\SLS (deleted all sub-folders except those dated 14th March = last successful Windows update): It did not help.
  

The laptop in part of a domain and I consider Resetting PC as the last resort.

 

December Cumulative Update

The Wu10 December Cumulative Update never installed. The entry says

Cumulative Update for Win10 v1909 (KB4530684) (2) not downloading. Last failed install attempt on 12/10/19 – Oxc 1900401

There have been no push attempts since and I do ask for Updates regularly. Today I got the January Cumulative which seemed to have some trouble but did install.

Should I do anything about December at this point? If so, what? (I don't do tech stuff)
