BitLocker is a built-in feature in Windows which encrypts all the files and data on the drive. And, just like the other features, it too is prone to errors. In this guide, we will tell you how to fix the various BitLocker errors in Windows 11.

Though, do remember that the BitLocker feature is not available for the Home edition of Windows 11, and you can only use it on the Pro edition. But, certain 2-in-1 laptops and tablets offer the Device Encryption feature, which is similar to BitLocker.

Also, since it’s a native Windows feature, there’s no additional cost involved and you can have it up and running without shelling an extra penny.

But if you are willing to shell a couple of bucks, there’s an amazing tool, Folder Lock, that does a lot more than just encrypt files and keeps your system more secure than ever.

4. Disable BitLocker in Windows 11

If nothing else works, you are left with no option but to disable Bitlocker in Windows 11. Though this will leave your drive relatively unsafe, it’s better than not being able to use the PC at all.

There are various ways to disable BitLocker. If you are able to boot Windows 11, go with the Control Panel method. In case you are unable to load the OS, you can always disable it by accessing Command Prompt from the Recovery Environment (RE).

How can I find the BitLocker recovery key in Windows 11?

1. If you are asked to enter the BitLocker recovery key, you can get it from your Microsoft account.
2. To find out the BitLocker key, find another PC with a working Internet connection, go to your Microsoft account’s recovery key section, sign in if prompted, and copy the key listed under the Recovery Key column.
3. Once done, enter this key and you should be able to sign in.

The BitLocker recovery key is a pretty long one, and if it has been somehow misplaced, you can easily access it from the Microsoft account.

However, if you end up entering the wrong pin or key, way too many times, it would take TPM to a locked state. In which case, you will have to wait for 2 hours before you get another chance to re-enter the recovery key.
