Explanation:
Virtual machine snapshots are file-based snapshots of the state, disk data, and configuration of a virtualmachine at a specific point in time. You can take multiple snapshots of a virtual machine, even while it is running. You can then revert the virtual machine to any of the previous states by App1ying a snapshot to the virtualmachine.
Taking a snapshot of a VM is to in essence freeze the current state and make it a parent disk based on currentstate, and at the same time create a child disk to capture all subsequent changes.

Snapshots require adequate storage space. Snapshots are stored as .avhd files in the same location at thevirtual hard disk. Taking multiple snapshots can quickly consume a large amount of storage space.
When you use Hyper-V Manager to delete a snapshot, the snapshot is removed from the snapshot treebut the .avhd file is not deleted until you turn off the virtual machine.
