I am attempting to do some quick cleanup on a Hyper-V host used for testing.
To do this I compacted the Hyper-V Virtual Disks.
- Open the Hyper-V Management console
- Right click on VM Guest
- Select Settings
- Select the Hard Drive for the VM Guest
- Click the Edit button
- Select Compact
- Click Finish
*note* you want to do this on dynamically expanding disk types
