How to Turn Off or Disable BitLocker on Windows 10

BitLocker is a Windows 10 security feature that encrypts your entire drive to protect your data if your device is lost or stolen. However, you may need to disable it for performance reasons, to use a different encryption tool, or because you no longer need that level of protection. This guide walks you through turning off BitLocker for your system drive or a secondary drive, using both the Control Panel and PowerShell methods. You will need administrative rights on the PC and, for the system drive, you must have the recovery key or be logged in with a Microsoft account that can retrieve it.

What You’ll Need

An administrator account on the Windows 10 PC.
Your BitLocker recovery key (if you are disabling on the system drive and you are not logged in with a Microsoft account).
Enough time for the decryption process to complete – it can take from a few minutes to an hour or more depending on drive size.

Step-by-Step

Back up important files. While decryption is safe, a power failure or system crash during the process can rarely cause data issues. Save critical documents to an external drive or cloud storage before starting.
Open Control Panel. Press Windows + R, type control, and press Enter. Alternatively, search for “Control Panel” in the Start menu.
Go to BitLocker Drive Encryption. In Control Panel, set the view to large or small icons, then click BitLocker Drive Encryption.
Find the drive you want to decrypt. You’ll see a list of drives. The system drive (usually C:) shows as “Operating system drive” and other drives are labeled with their letters and names.
Click “Turn off BitLocker” next to the drive you want to decrypt.
Confirm the action. A pop-up will ask “Do you want to turn off BitLocker?” Click Turn off BitLocker again.
Wait for decryption to finish. The drive will begin decrypting. You’ll see a progress bar in the BitLocker window. You can continue using your PC during this time, but avoid restarting or shutting down until it’s complete.
Verify the drive is decrypted. Once the progress bar disappears, the drive is no longer encrypted. You can check by reopening BitLocker Drive Encryption – it will show the drive as “Off”.

Alternative: Using PowerShell

Right-click the Start button and select Windows PowerShell (Admin) or Terminal (Admin).
Type the following command to disable BitLocker on a specific drive (replace E: with your drive letter):
Disable-BitLocker -MountPoint "E:"
Press Enter. The command will return immediately, but decryption continues in the background. To check progress, use:
Get-BitLockerVolume -MountPoint "E:"

Common Mistakes

Confusing “Turn off BitLocker” with “Suspend protection” – Suspending only pauses encryption temporarily (e.g., for a firmware update) and resumes automatically. To permanently disable, you must choose “Turn off”.
Not having the recovery key when decrypting the system drive – If you’re not logged in with a Microsoft account, Windows may prompt for the recovery key before allowing you to turn off BitLocker. Make sure you have it saved (e.g., printed, on a USB, or in your Microsoft account).
Shutting down during decryption – Interrupting the process can leave the drive in an inconsistent state. Wait until the progress bar is gone.
Attempting to disable on a drive that isn’t BitLocker-protected – If the option is grayed out, the drive isn’t encrypted, so there’s nothing to turn off.

Tips

If you’re disabling BitLocker to switch to a different encryption tool, consider decrypting first, then installing the new software – this avoids conflicts.
For laptops, ensure the device is plugged into AC power during decryption to prevent a battery drain that could cause a shutdown.
If you only need to use BitLocker temporarily, you can suspend protection instead of turning it off – this is faster and keeps your encryption keys intact.
After decryption, you may want to run a disk cleanup to remove any leftover BitLocker recovery files.

Troubleshooting

BitLocker options are grayed out or missing. This usually means your device doesn’t support BitLocker (e.g., Windows 10 Home edition) or the drive isn’t encrypted. If you’re on Home, BitLocker is not available; you’d need to upgrade to Pro or Enterprise. If the drive is encrypted but the option is still grayed out, try running the PowerShell command as admin.

You’re prompted for a recovery key you don’t have. If you’re logged in with a Microsoft account, go to account.microsoft.com/devices/recoverykey and sign in to find your key. If you used a work or school account, check with your IT department. If you can’t get the key, you won’t be able to disable BitLocker – and you may not be able to access the drive at all.

Decryption seems stuck at a certain percentage. This can happen on large drives or when the system is busy. Wait a few hours; if it doesn’t move, restart the PC. BitLocker will resume decryption automatically after boot.

You receive an error “The system cannot find the file specified” when using PowerShell. Make sure you’re using the correct drive letter and that the drive is BitLocker-encrypted. Also, ensure you’re running PowerShell as administrator.

Frequently Asked Questions

Q: Will disabling BitLocker delete my files?
A: No. Decryption only removes the encryption layer; all your files remain intact.

Q: How long does decryption take?
A: It depends on the drive size and speed. A typical 256GB SSD can take 10-30 minutes, while a 1TB HDD might take over an hour.

Q: Can I use my computer while BitLocker is decrypting?
A: Yes, you can continue using the computer, but avoid restarting or shutting down until decryption is complete.

Q: What’s the difference between “Turn off BitLocker” and “Suspend protection”?
A: Turning off permanently decrypts the drive. Suspending temporarily disables encryption until the next reboot – it’s used for system updates and resumes automatically.

Q: Do I need to disable BitLocker before selling or giving away my PC?
A: Yes, it’s strongly recommended to fully decrypt the drive (or better, format it) before handing over your device to protect your data.

Q: Can I re-enable BitLocker later?
A: Yes. After decryption, you can turn BitLocker back on anytime from the same Control Panel menu.
