Compact

Squeeze the empty bits out to reduce the amount of space consumes on host physical disk. It doesn't reduce the capacity of the guest disk.
Prerequisites:

• defrag the drive
• does not work on fixed VHDX
• virtual hard disk has to be NTFS formatted

1. Hyper-V manager - Edit disk
2. Choose action - compact

You cannot hibernate an operating system that runs on a VHD. However, sleep functionality is available.
