Bitlocker sucks

Question

Bit locker has invaded my computer. how do I get rid of it? [moved from Microsoft 365 Insider | Install, activate, and update | Windows]

Answer 1

Hi Stephanie Redmon,

I completely understand how frustrating and concerning it can be when BitLocker suddenly appears on your computer, especially if you don’t remember enabling it and it seems to be preventing you from using the device normally.

BitLocker is a built-in Windows security feature that encrypts the drive to protect the data. On some supported devices, Device Encryption may be enabled automatically during Windows setup. To narrow this down, are you still able to sign in to Windows or are you stuck on a blue BitLocker recovery screen asking for a 48-digit key?

1.If you can still sign in to Windows and simply want to turn encryption off:

• Back up any important files first.
• Open Settings > Privacy & security > Device encryption.
• If Device encryption is available, switch it to Off and follow the prompts.
• If you do not see that setting, search for Manage BitLocker from the Start menu.
• Open it, select Turn off BitLocker next to the encrypted drive, and allow Windows to decrypt the drive.

Please keep the computer connected to power while decryption is in progress and avoid interrupting the process.

2.If you are stuck on the BitLocker recovery screen:

You will need the matching 48-digit recovery key before Windows can unlock the drive. Using another device, sign in to the Microsoft BitLocker recovery key page with the Microsoft account that was used on this computer. Compare the Key ID shown on the recovery screen with the one listed in the account.

If this is or was a work or school device, the key may instead be held by the organization, so you may need to contact its IT administrator.

Please do not post the recovery key, Key ID, or a photo showing either of them on this public forum. Thank you so much for your understanding.

Answer 2

If the goal is to remove BitLocker or device encryption, the supported ways are:

1. Settings for Windows Home / Device encryption
   • Open Settings and search for device encryption.
   • Turn the toggle Off.
   • Decryption starts and must finish before encryption is fully removed.
2. Control Panel
   • Open the BitLocker Drive Encryption Control Panel applet.
   • Select Turn off BitLocker for the drive.
   • Confirm the prompt to start decryption.
3. Command Prompt
   • Run:

          manage-bde.exe -off C:
     

   • This starts decryption of drive C:.
4. PowerShell
   • Run:

          Disable-BitLocker -MountPoint C
     

Important:

• Turning off BitLocker decrypts the drive and removes associated protectors.
• Decryption can take a long time because the drive contents must be decrypted.
• Microsoft recommends decryption only when protection is no longer required, not as a troubleshooting step.
• Once encryption is off, data is less protected if the device is lost, stolen, or the drive is removed and connected to another device.

If the problem is repeated recovery key prompts, that can happen after hardware, firmware, or boot configuration changes, because BitLocker treats those changes as a possible unauthorized access attempt.
