说明
The Restore-Computer cmdlet restores the local computer to the specified system restore point.

System restore points and Restore-Computer are supported only on client operating systems, such as Windows 7, Windows Vista, and Windows XP.
示例
Example 1: Restore the local computer
PS C:\> Restore-Computer -RestorePoint 253
This command restores the local computer to the restore point that has sequence number 253.
Example 2: Restore the local computer with confirmation
PS C:\> Restore-Computer -RestorePoint 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"):
This command restores the local computer to the restore point that has sequence number 255. It uses the Confirm parameter to prompt the user before actually performing the operation.
Example 3: Restore a computer and check the status
PS C:\> Get-ComputerRestorePoint
PS C:\> Restore-Computer -RestorePoint 255
PS C:\> Get-ComputerRestorePoint -LastStatus
These commands run a system restore and then check its status.
The first command uses Get-ComputerRestorePoint to get the restore points on the local computer.
The second command restores 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 Restore-Computer forces a restart, this command would be entered after the computer restarts.
