Prevents access to encrypted data on a BitLocker volume.

Syntax

Lock-BitLocker
    [-MountPoint] <String[]>
    [-ForceDismount]
    [-Confirm]
    [-WhatIf]

Description

The Lock-BitLocker cmdlet prevents access to all encrypted data on a volume that uses BitLocker Drive Encryption. You can use the Unlock-BitLocker cmdlet to restore access.

You can specify a volume to lock by drive letter, or you can specify a BitLocker volume object. This cmdlet cannot lock a volume that hosts the operating system. If you attempt to lock an already locked volume, this cmdlet does nothing.

Examples

Example 1: Lock a volume

PS C:\> Lock-Volume -MountPoint "E:" -ForceDismount

This command locks the BitLocker volume specified with the Mount parameter. The command uses the ForceDismount parameter, so the cmdlet attempts to lock the volume even if it is in use.

Required Parameters

-MountPoint
