    After W7 to W10 upgrade - 2 MSR partitions


    I recently helped someone upgrade their system from Windows 7 to Windows 10 remotely.
    They are now running Windows 10 1909.

    Looking a Disk Management there are now 2 MSR (OEM Partition).

    I do not recall creating the EFI System partition or the MSR partitions when we first clean installed Windows 7 in 2014. But it has been far too long for me to remember.

    Also note: we had a glitch upgrading. This resulted in upgrading, restoring the W7 image backup, upgrading again. Which may explain the 2 MSR partitions.

    Questions:
    Can we delete one of these partitions?
    If so, how do we tell which one?

    Other questions:
    Will a Windows 10 Upgrade on an UEFI system create the EFI and MSR partitions on it's own?
    Even if the original Windows 7 installation was done with BIOS set to "Other OS"?

    After W7 to W10 upgrade - now 2 Recovery Partitions

    An easy way to tell which Recovery partition ('OEM') - which is what those are- is being used is to determine which is the more recent.
    Here's Minitool Partition Wizard: look at the date.

    Otherwise you can use these commands: here you can see partition 5 is in use.

    Win 10 will of course create the partitions appropriate to its environment - UEFI or MBR. It will be interesting to see what others say about your presumed UEFI configuration.

    Not sure how I "see" that partition 5 is in use.
    Is it because it has 237GB in the Offset column?
    Or because of something I'm looking at in reagentc /info?

    EDIT: Ah, I see it now.
    Thank You!
