    KB4566782 Cumulative Update Windows 10 v2004 build 19041.450 - Aug. 11 Win Update

    Got 3 updates this afternoon:
    2020-08 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004 for x64 based Systems (KB4569745)
    2020-05 Microsoft Edge Update for Windows 10 Version 2004 for x64 based Systems (KB4559309)
    2020-08 Cumulative Update for Windows 10 Version 2004 for x64 based Systems (KB4566782)

    Other than deleting all the Edge shortcuts, anything else I need to be worried about after these?

    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:

    Code:
    2020-08-25 18:14:10:989+0300
    1 182 [AGENT_INSTALLING_FAILED]

    Failure 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!
