This made the terminology consistent with System Center, and avoided confusion with respect to the Volume Shadow Copy Service (VSS) snapshots used by backup systems.

While the Hyper-V team did change the terminology, some of the cmdlet names remain unchanged. To restore a VM to a checkpoint, you use the Restore-VMSnapShot cmdlet.

When you create a checkpoint, Hyper-V temporarily pauses the VM. It then creates a new differencing disk (AVHD). Hyper-V then resumes the VM, which writes all data to the differencing disk. You can create multiple checkpoints for a VM.

Checkpoints are great for a variety of scenarios. They can be useful...
