I received a suggestion to download -
"Update for Microsoft Defender Antivirus antimalware platform - KB4052623 (Version 4.18.2105.3)"
and I updated it through Windows Update platform. But it resulted in -
"Status: Download error 0x80070643"
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)
After this my Microsoft Defender Antivirus Threat service is stopped and not working ever since (restarting the service results in error also).
Please help!

Hello @imanojpatel,
Please run Windows Update troubleshooter from Settings app > Update & security > Troubleshoot > Additional troubleshooters. See if it works.
If that doesn't work, try this:
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.
Let us know if this helps!

Hi @Kapil Arya
I tried the steps suggested by you and also performed the well known basic update troubleshooting actions but nothing ever worked out.
This is what i keep getting always. I'm facing this issue right from 30th April 2021.
I also tried to install the update manually through MS update catalog, but that too didn't worked out...!!!

If you are in the insider program, please analyze the execution of a clean installation of Windows - but everything will be removed please make copies of your personal files:
Using ISOs - Windows Insider Program | Microsoft Docs
Using ISOs - Windows Insider Program | Microsoft Docs
Sometimes an in-place upgrade helps, but it doesn't always work.

Download Windows 11 (microsoft.com)
After downloading the tools for creating media, you can follow the steps that I suggested earlier :)
