A Hyper-V checkpoint is a version of a VM at a specific point in time. As a best practice,
it is recommended that you create a VM checkpoint of your deployment before making
any changes to the system.
To create a Hyper-V checkpoint:
From the Hyper-V Manager, select your virtual machine, right click and select
Checkpoint.
The Hyper-V Manager creates a checkpoint with the current timestamp.
Use the bottom right menu to rename, export, or revert checkpoints.
