    Creators Update creates new hidden partition PQ MirOS


    Howdy !
    I use Acronis to regularly re-image my computers, so I like my PC's running in Legacy mode (not UEFI) and without all the hidden and recovery partitions. I just did the Creators Update and it has ANNOYINGLY created a 3rd partition, called "Windows RE Hidden, PQ, MirOS". It's less than 400MB so it's not an issue of space, but I just don't like them doing this.

    Does anyone know if there is a way to stop this from happening ? I don't want to just delete the partition, but if I do a clean install, or restore last month's image and re-do the update - does anyone know if there is a way to stop these annoying extra hidden partitions ?

    Hi ppm, yes, FCU makes new recovery partition instead of C:\Recovery folder. Don't know how to block it but I know how to revert it into previous state but it it is not so easy.

    1. Extracting Windows Recovery Environment files from Recovery partition:
    - run diskpart at elevated command prompt, then use following commands
    list volume
    select volume <number_of_recovery_volume_identified>
    assign letter=R
    exit

    - in Explorer, copy WindowsRE folder from drive R: to desktop; it holds 3 files including winre.wim (changing source ownership/permissions may be needed)

    2. Deleting recovery partition:
    - run diskpart at elevated command prompt, then use following commands
    list disk
    select disk <number_of_system_disk>
    list partition
    select partition <number_of_recovery_partition>
    && Be sure to enter correct number of RECOVERY partition, it will be deleted!
    delete partition override
    exit

    - in Disk Management snap-in, expand your C: partition to empty space

    3. Copying Recovery files to previous location:
    - in Explorer, copy WindowsRE folder from desktop to C:\Recovery folder (changing target ownership/permissions may be needed)

    4. Registering current location of WindowsRE folder:
    - type following commands at elevated prompt
    reagentc /setreimage /path C:\Recovery\WindowsRE
    reagentc /enable


    5. Deleting orphaned recovery entry from BCD store:
    - type following command at elevated prompt
    bcdedit /enum osloader
    - find entry which includes wrong path to non-existent recovery partition in row named Device
    - type following command at elevated prompt
    bcdedit /delete {identifier_of_bad_entry} && Be sure to enter correct ID of bad entry as it will be deleted

    6. Testing new WinRE:
    - at logon screen, do Shift + Restart etc.

    I've had bad experiences with Acronis products. I recommend Macrium Reflect Free which is reliable and well supported & engineered.
