Turning off BitLocker in Windows 11 decrypts the protected drive. This is different from suspending BitLocker, which temporarily stops some protection while leaving the drive encrypted. Before decrypting a drive, back up important files and make sure you can access the BitLocker recovery key.
Before You Turn Off BitLocker
- Back up important files.
- Find and save the correct BitLocker recovery key.
- Connect a laptop to power.
- Make sure you have administrator access.
Keep the recovery key somewhere separate from the encrypted PC. A recovery key may be needed if Windows detects a security or hardware change before decryption is complete.
How to Turn Off BitLocker
- Open Start and search for Manage BitLocker.
- Open the BitLocker Drive Encryption control panel.
- Find the drive you want to decrypt.
- Select Turn off BitLocker.
- Confirm that you want to decrypt the drive.
- Leave the computer powered on while decryption proceeds.
The exact BitLocker controls available depend on your Windows edition, device, drive, and organization policy. Some Windows devices use Device Encryption with a simpler interface instead of the full BitLocker management experience.
Turn Off vs. Suspend BitLocker
Turn off BitLocker decrypts the drive and removes BitLocker protection. Suspend protection leaves the drive encrypted but temporarily relaxes the normal protection mechanism. Suspending can be appropriate for certain firmware or hardware maintenance when trusted instructions specifically call for it.
Will Turning Off BitLocker Delete Files?
Normal BitLocker decryption is designed to decrypt the existing data rather than erase it. Even so, encryption changes are a poor time to discover that an important file was never backed up. Make a backup before starting.
Why Is Decryption Taking So Long?
Decrypting a large drive can take time. Drive size, storage speed, current activity, and hardware can affect how long it takes. Avoid unnecessary shutdowns or storage changes while Windows is decrypting the drive.
Should You Remove BitLocker?
Do not disable encryption merely as a general performance tweak. BitLocker protects data if a device or drive is lost or stolen. Turn it off when you have a specific reason and understand the security tradeoff.
Summary
To remove BitLocker protection, open Manage BitLocker, choose the drive, select Turn off BitLocker, and allow Windows to decrypt it. Back up your data and secure the recovery key first. If you only need a temporary maintenance exception, suspending protection may be more appropriate than decrypting the drive.
