    System restarts at 91% of Microsoft Defender Offline Scans!


    It's been more than a week since my laptop restarts at 91% of Microsoft Defender Offline Scans. There are no notification of scan completion and the virus and threat protection section shows the last scan was a full scan (a week ago). What should I do?

    Thank you in advance. Have a nice day.

    Microsoft Defender Offline Scan

    Restored the Macrium Image and got my Recovery partitions back:

    So as expected, I had a bunch of updates to do:

    After the updates, I gave Microsoft Defender Offline a try and it worked!

    And this just shows that I'm back at the latest version build of 20H2:

    This one was my fault and I admit I was the culprit of my own troubles. It was just a coincidence that I used Partition Wizard around the same time the Cumulative Updates were going on from Oct 28th to November 11th and it gave me the suspicion to suspect them being responsible for the Offline scan problem.

    I mean who the heck would of ever thought that a Recovery Partition would have anything to do with an Offline Scan in an Online world?

    A special thanks to OldNavyGuy for his suggestion that a Windows Recovery Partition being deleted was the problem.

    The same thing happened to me...because I deleted the Recovery Partition on one of our systems.

    That also broke Reset this PC in Settings > Update & Security > Recovery

    I tricked myself into thinking that the space was up for grabs -

    Uh...no -

    (Note: MiniTool Partition Wizard calls Disk Management "Disk 0" - "Disk 1")

    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).
