Update for Microsoft Defender Antivirus antimalware platform - KB4052623 (Version 4.18.2210.6) is unable to install ( Error 0x80070643 )

Question

Hello,

Every time I try to re-update / check for updates in Windows 10 OS, it shows "Update for Microsoft Defender Antivirus antimalware platform - KB4052623 (Version 4.18.2210.6)" available. And when it starts to install, it gets stuck at 0% for several minutes then it shows the following message,

"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643)"

And when I retry, it again shows the same error, seems like I am stuck in a loop.

I have tried running windows update troubleshooter, and it's showing that it has resolved the update problem, but that error keeps coming.

I have also updated .NET Framework but the issue is still there.

Please Help.

Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

Actually, I have the same problem and by following the steps below fixed my issue, I know some of these steps are already done, you have just skipped it if you think it will have the same result.

Reset Windows update components:

Open Powershell with Admin or CMD with Admin (Press Windows key + X then click Windows Powershell(Admin))

Copy each line of command to Powershell then press enter (one line at a time)

net stop bits

net stop wuauserv

net stop appidsvc

net stop cryptsvc

Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*"

rmdir %systemroot%\SoftwareDistribution /S /Q

rmdir %systemroot%\system32\catroot2 /S /Q

regsvr32.exe /s atl.dll

regsvr32.exe /s urlmon.dll

regsvr32.exe /s mshtml.dll

netsh winsock reset

netsh winsock reset proxy

net start bits

net start wuauserv

net start appidsvc

net start cryptsvc

-Once done restart the device and check.

If none will work from the above solution, I suggest doing an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

Note: before doing this make sure to create a restore point: https://support.microsoft.com/en-hk/help/402753...
