Windows 10: Offline scan and Event Viewer troubles

Hi everyone I was hoping someone here could help me with an issue I am having. Whenever I run offline scans with windows defender it never reaches 100% it stops at around 91%. I was told I could check event viewer on its progress so I did. However when I checked, it had a code of 5007 instead of the typical 1001 and it mentioned that “Microsoft Defender Antivirus configuration has changed. If this was an unexpected event you should review the settings as this may be the result of malware.” I constantly scan my computer with both windows defender and malwarebytes using quick, full an

Event viewer

I suggest you re-install the video driver. I'll add a few words of explanation about Event viewer in a moment. They won't affect the need to reinstall that driver as your first step. Denis

 

Q> Windows Defender Offline Scan (Windows 10 Pro_x64) Event ID

Would you mind elaborate your issue in details?

If anything detects during Windows Defender Offline, it will be appeared in Windows Defender History and under malware list and general information for scan should be appeared in Windows Event Viewer.

 

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.
