    The in place upgrade repair should install only one recovery partition on the right side so that it can be modified by future upgrades.
    Understood.

    I think I want both the Recovery Partitions back even though I suspect only one is responsible for the Microsoft Defender Offline Scan not working.

    In your most humble and extremely vast knowledge, do you think this is just a matter of choosing between which method I feel more comfortable with or are you suggesting my Macrium Image is not the way to go on this?

    The Macrium image can almost always be used.

    Only one recovery partition can be used.

    So there is no advantage in consuming the drive space.

    Once you have the drive with the typical partitions Macrium will create a new image which can be used for restoration.

    The Factory Recovery Partition along with the Windows Recovery Partition took up less than 2GB of space. Aside from the fact that space being consumed is of no concern, I may just rely on Macrium to work its magic and if I so desire, just remove only the Factory Recovery Partition this time and leave the Windows Recovery Partition alone.

    They are user preference.

    This is an example of 2 Windows recovery partitions on the same drive:

    Microsoft Defender Offline Scan-ten-forums-recovery-partition.png

    There was insufficient free space in the recovery partition on the left side of the primary partition.
    So during an upgrade Windows created a new recovery partition on the right where there was free space.

    The recovery partition on the left was disabled.

    So there is only one enabled windows recovery partition.

    I've never seen a configuration that places a Recovery Partition before the System Partition. I guess now I have!

    My Factory Partition was used to restore the machine to the way it was when it left the factory and was placed just at the end of Partition "C". Then Windows 10 came along and placed the Windows Recovery Partition at the very end of the disk drive like it was suppose to.

    This is the default UEFI partition for the latest Windows versions:

    https://docs.microsoft.com/en-us/win...ive-partitions

    Partition layout
    The default partition layout for UEFI-based PCs is:

    a system partition, an MSR, a Windows partition, and a recovery tools partition.

    For left sided UEFI recovery partitions see Windows 10 prior to 2017.

    Just from reading the first few paragraphs of the link you posted, I'm definitely in for a good read.

    I've read so many of your posts over the years and never directly needed your help in the BSOD department; but I sure thank you kindly for what you do and the countless people you have helped.

    Always appreciated zbook ---- always!

    Well, coming up on 2a.m. soon; so I'm going to get started on this because after 2a.m. Hughesnet allots its Bonus Data and it doesn't count against my capped data. So I'm sure I'm going to have some updates to reinstall.

    I'll post back if this fixes the Microsoft Defender Offline Scan and then mark this as solved.

    If it does work, I'm just wondering why for the last three years none of the other forums posted a solution. Of course most of the threads I had read were closed or just never consolidated.

    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:

    Microsoft Defender Offline Scan-version.jpg

    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.
