Windows 10: Failed to install 2020-08 Cumulative Update/KB4566782

Hello, I've run into the following issue while updating Windows 10.


Windows Update tried to install the 2020-08 Cumulative Update. It downloaded, installed and requested to restart. Upon restarting, it blue-screened stating SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. It looped once more with the same problem and eventually went into self-recovery mode, automatically uninstalling the update and then booting into Windows without issues.


The 2020-08 Cumulative Update no longer appears through Windows Update. I checked my installed version 19041.388 and indeed it is left behind the latest version is 19041.450. The patch responsible for upgrading is KB4566782, so I headed over to Microsoft Update Catalog found it and tried to install it manually. The result was exactly the same as before, failure due to SYSTEM_THREAD_EXCEPTION_NOT_HANDLED.


Log from C:\Windows\SoftwareDistribution\ReportingEvents.log:

2020-08-25 18:14:10:989+03001 182 [AGENT_INSTALLING_FAILED]101 {6D40EE5F-A7BA-4961-A4FD-CE99061CCF79}501 800f0845 wusaFailure Content Install Installation Failure: Windows failed to install the following update with error 0x800f0845: Update for Windows KB4566782.fR7JVuk2MkqL3IDk.2.1.0.3.0.0


I have verified my Windows installation through the Deployment Image Servicing and Management DISM tool as well as 'sfc /scannow' but none of these tools found any issues.


Any ideas/suggestions on how to overcome this issue? Thanks in advance!

:)

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.
