Virtual Machine Settings for Snapshots
The Virtual Machine Settings window lets you configure two options for snapshots:
Open the window with VM > Settings > Options > Snapshots.
GeneralDisabling Snapshots
VMware Workstation overall speed and response times are improved when you have snapshots disabled. Without snapshots, a virtual machine runs the same way a physical computer does. All changes made to a virtual machine are permanent and you cannot restore an earlier state.
If no snapshots exist for the current VM, you can disable snapshot functionality by selecting Disable snapshots.
If any snapshots exist for current virtual machine the Disable snapshots check box is disabled. If you want to disable snapshot functionality, you must first delete all snapshots for the current VM. Refer to Deleting a Snapshot.

For example, an instructor may need to discard student answers for a computer lesson when a virtual machine is powered off at the end of class.
Take a new snapshottakes a new snapshot of the virtual machine state after it is powered off. This is useful to preserve milestones automatically. The name of this snapshot is the date and time of the power off. The Snapshot Manager description says "Automatic snapshot created when powering off."
