How to Disable and Turn Off BitLocker Drive Encryption in Windows OS

BitLocker is a full disk encryption feature included in certain versions of Windows, starting with Windows Vista, to protect data by encrypting entire volumes. It uses AES encryption algorithms with 128-bit or 256-bit keys to encrypt the full contents of drives.

Benefits of BitLocker:

  • Prevents unauthorized access to data on lost, stolen or decommissioned devices
  • Protects against offline attacks that bypass the Windows authentication methods
  • Meets regulatory compliance requirements for data protection in some industries

When You May Want to Disable BitLocker

There are a few cases when you may need to temporarily disable or fully turn off BitLocker encryption on a drive:

  • To troubleshoot drive errors or boot issues that could be related to BitLocker
  • When travelling internationally to countries with encryption regulations
  • To change drive partitioning or file system formats
  • To decrypt a drive before migrating or repurposing a Windows device

Methods to Disable or Turn Off BitLocker

There are several methods you can use to disable or turn off BitLocker drive encryption in Windows, depending on your version and edition.

Using BitLocker Control Panel (Windows 10/11 Pro/Enterprise)

The BitLocker control panel provides an easy GUI method to manage drive encryption.


  1. Search for “BitLocker” in the Windows Start Menu to open the BitLocker Drive Encryption control panel
  2. Click “Turn off BitLocker” for the drive you want to decrypt
  3. Confirm that you want to turn off encryption and start the decryption process

This will permanently disable BitLocker protection on that drive until you choose to turn it back on.

Using Command Prompt

Advanced users can use the manage-bde command line tool to disable BitLocker encryption.


  1. Open an elevated Command Prompt as Administrator
  2. Run command:
   manage-bde -off X:

(Replace X with drive letter)

  1. Confirm decryption process has started

This will immediately start decrypting the drive contents.

Using PowerShell

You can script BitLocker encryption changes across multiple drives with PowerShell cmdlets.


  1. Open PowerShell as Administrator
  2. Run command: Disable-BitLocker -MountPoint "X:" (Replace X with drive letter)
  3. Confirm the decryption process has initiated

This will disable encryption and begin decrypting the data on the specified mount point.

Using Group Policy

IT admins can use Group Policy to disable BitLocker encryption across multiple devices in Active Directory.


  1. Open the Group Policy Management Editor
  2. Navigate to Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption
  3. Set the policy for fixed data drives to “Deny write access to fixed drives not protected by BitLocker” and select Disabled
  4. Click Apply

This will decrypt BitLocker-protected fixed drives when machines apply new Group Policy.

Using Device Encryption Settings (Windows 10/11 Home)

Some editions of Windows enable transparent “device encryption” by default using device credentials.

Steps to disable:

  1. Search for “Device encryption”
  2. Open Device encryption settings
  3. Toggle “Device encryption” to “Off”
  4. Confirm decryption on the system drive

This disables the built-in device encryption for drives encrypted with device credentials.

What Happens When You Disable BitLocker

  • All encryption key protectors are removed from the drive
  • Encrypted drive contents start being decrypted
  • Data on the drive is no longer protected from unauthorized offline access
  • The BitLocker lock icon no longer appears on the drive

The decryption process runs in the background, so you can continue accessing files on the drive. But allowing sufficient time for full decryption is recommended before repurposing or decommissioning the device.

Best Practices for BitLocker Management

Properly managing BitLocker encryption involves careful planning and standard procedures to prevent data loss scenarios.

Recommended practices include:

  • Maintain an up-to-date database of BitLocker recovery keys
  • Configure a waiting period before starting encryption to back up data
  • Suspend BitLocker temporarily when making major system changes to avoid boot issues
  • Use centralized management tools to monitor encryption status across all endpoints
  • Disable BitLocker prior to drive formatting, partitioning or reimaging
  • Ensure decrypted drives are fully decrypted before decommissioning devices

Implementing organized BitLocker management processes is essential to getting the full security benefits of drive encryption while avoiding potential disruption to users and operations.


BitLocker drive encryption provides important data protection capabilities by preventing unauthorized access to lost, stolen or decommissioned devices. But there are times when temporarily disabling or fully turning off BitLocker becomes necessary for troubleshooting or administrative tasks.

Using the proper methods for your Windows version, like the BitLocker control panel, command line tools, or centralized management policies, you can decrypt drives with minimal disruption to users. Just be sure to allow time for full decryption before repurposing encrypted devices.

With the right balance of security and accessibility, BitLocker can significantly improve your data protection without impeding other system administration needs. Careful management is key to avoiding issues with encrypted drives.
