    Hi @Aziz Husain ,

    It's not possible to shrink a VHDX file because you cannot shrink the volume on the virtual disk, for more information read the blog post here:

    Assuming that you are using a currently-supported version of Hyper-V (not 2008 R2 or older), then you can create a VHDX from the VHD.

    1. Shut down the VM.
    2. Detach the VHD from the VM.
    3. Create a new dynamically expanding VHDX from the source VHD (screenshot below).
    4. Shrink the newly created VHDX.
    5. If you wish, convert to fixed.
    6. Reattach the final VHDX to the VM.
    7. Test that everything works.
    8. Delete the old VHD and any intermediary VHDXs.
