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 on TechNet.

Examples

Example 1: Disable BitLocker for a volume

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

This command disables BitLocker for the specified BitLocker volume. BitLocker begins decrypting data on C: immediately.

Example 2: Disable BitLocker for all volumes

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

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.

Required Parameters

Specifies an array of drive letters or BitLocker volume objects. The cmdlet disables protection for the volumes specified. To obtain a BitLocker volume object, use the Get-BitLockerVolume cmdlet.
