Disable-BitLocker

Disables BitLocker encryption for a volume.

Syntax

Parameter Set: __AllParameterSets
Disable-BitLocker [-MountPoint] <String[]> [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Disable-BitLocker cmdlet disables BitLocker Drive Encryption for a BitLocker volume. When you run this cmdlet, it removes all key protectors and begins decrypting the content of the volume.

If the volume that hosts the operating system contains any automatic unlocking keys, the cmdlet does not proceed. You can use the Clear-BitLockerAutoUnlock cmdlet to remove all automatic unlocking keys. Then you can disable BitLocker for the volume.

For an overview of BitLocker, see BitLocker Drive Encryption Overview (http://technet.microsoft.com/en-us/library/cc732774.aspx) on TechNet.

PS C:\> Disable-BitLocker -MountPoint "C:" 

Example 2: Disable BitLocker for all volumes

This example disables BitLocker encryption for all volumes.

The first command uses Get-BitLockerVolume to get all the BitLocker volumes for the current computer and stores them in the $BLV variable.

The second command disables BitLocker encryption for all the BitLocker volumes stored in the $BLV variable. BitLocker begins decrypting data on the volumes.


PS C:\> $BLV = Get-BitLockerVolume
PS C:\> Disable-BitLocker -MountPoint $BLV
