Example 1

C:\PS>restore-computer -RestorePoint 253

Description
-----------
This command restores the local computer to the restore point with sequence number 253.

Because the RestorePoint parameter is positional, you can omit the parameter name.







Example 2

C:\PS>restore-computer 255 -confirm

Confirm
Are you sure you want to perform this action?
Performing operation "Restore-Computer" .
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"):

Description
-----------
This command restores the local computer to the restore point with sequence number 255. It uses the Confirm parameter to prompt the user before actually performing the operation.







Example 3

C:\PS>Get-ComputerRestorePoint

C:\PS> Restore-Computer -RestorePoint 255

C:\PS> Get-ComputerRestorePoint -LastStatus

Description
-----------
These commands run a system restore and then check its status.

The first command uses the Get-ComputerRestorePoint cmdlet to get the restore points on the local computer.

The second command uses Restore-Computer to restore the computer to the restore point with sequence number 255.

The third command uses the LastStatus parameter of Get-ComputerRestorePoint cmdlet to check the status of the restore operation. Because the Restore-Computer command forces a restart, this command would be entered when the computer restarted.
