Overview

In virtual desktop environments, BitLocker may interfere with drive access or cause issues during provisioning and reimaging. This article explains how to disable BitLocker on a virtual disk to prepare for template creation


Prerequisites

  • You must run these commands as a local administrator.

  • Do not power off the computer while the drive is decrypting.

  • Decryption time varies depending on disk size and performance.



Procedure

1) Open PowerShell as an Administrator

  • Right-click Start

  • Select Windows PowerShell (Admin)


2) Disable BitLocker on the C: drive

     Run the following command:

Disable-BitLocker -MountPoint "C:"

This command begins decrypting the drive in the background.



3) Verify decryption status

     To check progress and confirm completion, run:

Get-BitLockerVolume

Confirm the output shows:

  • VolumeStatus : FullyDecrypted

Decryption may take several minutes depending on disk size and disk speed.


4) Restart the machine

  Once the drive is fully decrypted, restart the computer to ensure all BitLocker services and handles are cleared.
