Module:
bitlocker
Removes a key protector for a BitLocker volume.

Syntax 

Remove-BitLockerKeyProtector
      [-MountPoint] <String[]>
      [-KeyProtectorId] <String>
      [-WhatIf]
      [-Confirm]
      [<CommonParameters>]

Description

The Remove-BitLockerKeyProtector cmdlet removes a key protector for a volume protected by BitLocker Drive Encryption.

You can specify a key protector to remove by using an ID. To add a protector, use the Add-BitLockerKeyProtector cmdlet.

If you remove all the key protectors for a BitLocker volume, BitLocker stores the data encryption key for the volume without using encryption. This means that any user that can access the volume can read the encrypted data on the volume unless you add a key protector. Any encrypted data on the drive remains encrypted.

We recommend you have at least one recovery password as key protector to a volume in case you need to recover a system.

For an overview of BitLocker, see BitLocker Drive Encryption Overview on TechNet.

Examples

Example 1: Remove a key protector for a volume 

PS C:\> $BLV = Get-BitLockerVolume -MountPoint "C:"
PS C:\> Remove-BitlockerKeyProtector -MountPoint "C:" -KeyProtectorId $BLV.KeyProtector[1]

This example removes a key protector for a specified BitLocker volume.

The first command uses Get-BitLockerVolume to obtain a BitLocker volume and store it in the $BLV variable.

The second command removes the key protector for the BitLocker volume specified by the MountPoint parameter. The command specifies the key protector by using its ID, contained in the BitLocker object stored in $BLV.
