Windows 10: Windows Defender Offline Scan is not working

Can you solve this problem as I cannot perform a "Windows Defender Offline Scan" in my Windows 10 pc. When I click on "Settings > Update and Security > Windows Security > Virus and threat protection > Scan Options > Microsoft Defender Offline Scan > Then I click on Yes but the Scan did not start , even it did not restart my pc to start the scan. I ran "sfc /scannow" and "DISM" tool to check whether any system files are corrupted or not , it repaired those files and I restarted my pc but the MS Defender Offline Scan did not start to scan my pc. I created a new user account but

Defender Periodic Scanning or Offline Scanning?

That link does suggest it's useful to use Defender offline scanning in addition to periodic scanning and a third party real time anti virus (e.g. Kaspersky).

 

offline scan by win defender

Hi,

To further assist you with your concern with Windows Defender, follow the steps below:

• Open the Run window by pressing Window + R button.
• Then type services.msc and hit "Enter".
  
• Look for Windows defender service in the list and right click on it and select start.
• Once Windows defender is opened try to do the offline scan on that window.

Let us know how it goes.

 

Microsoft Defender Offline Scan

I'll give this thread a little bump and explain what I have tried so far to no avail. After hours of extensive reading about how WDO and now Microsoft Defender Offline scans are not working for some since as far back as 2017 for Windows Defender Offline, I had removed all remnants of Malwarebytes from my registry in an attempt to see if any of those entries were conflicting with the Microsoft Defender Offline Scan.

No dice!

The second thing I tried was a Restore Health function with the DISM command and it reported a successful operation and still the Offline scan won't initiate. Yes, I rebooted after the DISM Restore Health Command.

No Dice gain!

Some articles suggested a repair install; but honestly at this point, if sfc /scannow isn't flagging anything and my OS is completely operational with no Event Viewer Errors and no Reliability History issues of any kind (especially Critical Events) I really can't justify using a repair install that probably will not fix it either.

I mean I literally have no indication that any corruption exists anywhere throughout the OS; yet something that worked before the Cumulative Update is now broken and not a peep of it has been mentioned in any documentation that I came across lately that it is a known issue with the November 11th Cumulative Update for systems on 20H2.

Sure I could restore a full backup image I have to prove that Microsoft Defender Offline Scan worked prior to the update; but who would really be interested in that proof?

I don't understand why this feature was broke on some systems since 2017 and mine remained immune until just now.

So I would really like to hear suggestions if anyone knows how to get this feature working again on this latest Version and Build listed under my Avatar.

Thanks to any and all who have knowledge about how to fix this or if they heard a rumor that this is another feature that is being done away with and I just haven't heard yet.
