Description

The Restart-VM cmdlet restarts a virtual machine. Running this cmdlet results in a "hard" restart, like powering the computer down, then back up again. This can result in data loss in the virtual machine.

Examples

Example 1

PS C:\> Restart-VM Win7
Confirm
Are you sure you want to restart virtual machine "win7"?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): y

Performs a hard restart of virtual machine Win7. This is equivalent to turning off the power to the virtual machine and then restarting it.
