    Ooops!... That might explain it. Mine was OK in 18363.657 as I don't remember looking at it in 18363.697.
    So it might be that MS broke Disk Management.
    You could uninstall the last Win 10 Update.

    A windows update was just performed.
    It is now 10.0.18363.720.



    Windows Recovery partition missing from Volume list of Disk Management-ten-forums-disk-management-after-windows-update-3-14-2020.png



    Diskpart displayed 6.98 GB
    diskpart det partition displayed 7148 MB Fs RAW
    reagent /c displayed disabled
    reagent /c enable displayed The Windows RE image was not found.

    So it appears for now that this new problem is related to Windows updates.

    Isn't that wonderful... It seems that my "display" issue, is minor compared to this one, which displays Recovery partition correctly!

    What I see with Partition 4 - which is clearly the Recovery Partition
    WinRE is present and WinRE is registered....
    With that said - the GPT Attributes listed by Powershell are slightly off for that partition
    and should be > gpt attributes=0x8000000000000001
    rather then current > gpt attributes=0x8000000000000000

    change final digit to 1 and verify the results

    Not sure if reason - but the partition is set to a different then normal Attrib
    and I know that changing the 8 or final digit in the past had an effect..

    You can also checkout diskpart GPT Attributes help on-line

    As I said before...since Jimmy is here, if there is a a solution, it will be given!

    As Jimmy suggested changing the last bit of the partition's attribute from 0 to 1 (made the partition Required), takes care of the problem.
    The question is, why this should be done as the partition's attribute was never changed from what the Windows 10 installation set it and it was functioning perfectly before...but I guess that is something MS has to answer!!

    Just to make clear what needs to be done, in case someone else faces the same issue:

    Before:
    Windows Recovery partition missing from Volume list of Disk Management-diskmanagment-before.png

    After running the following diskpart coammands:
    Code:
    list disk
    select disk 0  <-- the disk with the Recovery partition
    list part
    select part 4  <-- the Recovery partition
    detail part
    gpt ATTRIBUTES=0x8000000000000001
    Windows Recovery partition missing from Volume list of Disk Management-diskmanagment-aftert.png

    A huge thanks to Jimmy for his precious help!!!

    And one last, more technical, note:
    GPT attributes
    - 0x0000000000000001. Specifies that the partition is required by the computer to function properly.
    - 0x8000000000000000. Specifies that the partition will not receive a drive letter by default when the disk is moved to another computer or when the disk is seen for the first time by a computer.

    For EFI partitioning det par displays attributes.
    For MBR partitioning det par does not display attributes.
    What should be checked in MBR?

    Check the remarks in here
    GPT and MBR attributes behave differently on volumes

    And one final thing:

    I will not mark the issue as "Solved" yet, until we see if this is an intentional change the Redmond geniuses have decided, (i.e. show the Recovery partition in volume list, only if it's "Required"), or someone screwed up with the latest update.

    Something I noticed, in the screenshots above which probably shows that the problem, although seems to be solved by the recommendation of @Kyhi, is most likely a screw-up from Microsoft.

    In the two screenshots above, in the first one the EFI partition and in the second one both the EFI and Recovery partitions show as 100% free space, i.e. not used at all.
    This is not the case for both of them as they both have data written.

    So it seems that it's not just the Recovery partition not showing in the Volume list, but a more complicated issue, which needs Microsoft's attention!
