    I am using a MBP with 10.14.5 and Parallels 13. I have a W10 VM that I had set to use 40 GB disk space.

    I installed the latest W10 updates and got an info that 1903 is available but that I need an additional 12.9 GB of free space. In settings, system updates I checked the disk space and it showed total 38.8 GB, used 35.9 GB and free 2.86 GB.

    I shutdown the VM, and increased the HD space to 55GB. Started the VM again, but in system update check disk space I still see the 38.8 GB total disk space. Because the increase to 55GB is not recognized in W10 I cannot install 1903.

    Am I missing some changes in the Windows setup or configuration? How can I get Windows to recognize the additional space I assigned?

    Hi Gerd,
    please make a backup copy of your VM and try the following steps:
    1. Locate your Virtual machine in Finder
    2. Right click on the *.pvm file of your virtual machine -> choose Show Package Contents
    3. In Mac OS X, go to Applications > Utilities and launch Terminal. Type the following but do not execute:

      prl_disk_tool check --hdd

    4. Drag the *.hdd file into Terminal and drop it right next to "prl_disk_tool merge --hdd ". In Terminal you will see something like this:
      prl_disk_tool check --hdd /Users/Username/Documents/Parallels/Windows\ 7.pvm/Windows\ 7-0.hdd

      Note: There should be a space between '--hdd' and 'Users/Username...'
    5. Press Enter/Return key to run the command and attempt to fix the disk consistency.
    6. When the operation is complete, try resizing the hard disk again.
