The additional advantage Windows PowerShell offers is the ability to decrypt multiple drives in one pass. If a user wishes to check the status of the decryption, they can use the following command:įigure : Manage-bde decryption process indicatorĭecrypting volumes using the BitLocker Windows PowerShell cmdletsĭecryption with Windows PowerShell cmdlets is straightforward, similar to manage-bde. This command disables protectors while it decrypts the volume and removes all protectors when decryption is complete. Manage-bde uses the -off command to start the decryption process. Decryption with manage-bde offers the advantage of not requiring user confirmation to start the process.

With decryption complete, the drive will update its status in the control panel applet and is available for encryption.ĭecrypting volumes using the manage-bde command line interfaceĭecrypting volumes using manage-bde is very straightforward. Selecting the notification area icon will open a modal dialog with progress.įigure : Decryption progress from notification area The control panel applet does not report decryption progress but displays it in the notification area of the task bar. With Turn off BitLocker confirmed, the drive decryption process will begin and report status to the control panel applet.įigure : Confirmation dialog prior to starting decryption Once selected, the user chooses to continue by clicking the confirmation dialog. After opening the BitLocker control panel applet, users will select the Turn off BitLocker option to begin the process.įigure : Turn off BitLocker option for an encrypted volume The control panel can be called from Windows Explorer or by opening the applet directly. We will discuss each method further below.ĭecrypting volumes using the BitLocker control panel appletīitLocker decryption using the control panel applet is wizard driven. BitLocker can be removed from a volume using the BitLocker control panel applet, manage-bde or Windows PowerShell cmdlets. BitLocker encryption should not occur as a troubleshooting step. Decryption should occur when protection is no longer required. If the encryption uses the Used Disk Space Only option described later in this document, this step takes only a few seconds and incorporates well into regular deployment processes.ĭecrypting volumes removes BitLocker and any associated protectors from the volumes. This is done with a randomly generated clear key protector applied to the formatted volume and encrypting the volume prior to running the Windows setup process. In Windows Server "8" Beta, administrators can enable BitLocker prior to operating system deployment, from the Windows Pre-installation Environment. Provisioning BitLocker during operating system deployment
This command will display information about the encryption method, volume type, key protectors, etc.įigure : Detailed output of BitLocker status using Windows PowerShell To get information that is more detailed on a specific volume, use the following command:
Using the Get-BitLockerVolume cmdlet, each volume on the system will display its current BitLocker status. Like manage-bde, Windows PowerShell includes the advantage of being able to check the status of a volume on a remote computer. Windows PowerShell commands offer another way to query BitLocker status for volumes. Checking BitLocker status with Windows PowerShell
