I. What is BitLocker encryption?

BitLocker encryption is a built-in feature of Windows devices. It was first introduced in the Vista system and has since become an integral part of the Windows operating system. BitLocker supports full-disk encryption using the AES algorithm and CBS (Cipher Block Chain). This ensures that the entire hard disk or partition is encrypted, making the data stored within it highly secure. To access the data on the hard disk, a key is required.
To recover lost data encrypted with BitLocker, use professional data recovery software. Remember not to save new data before recovery to prevent damage to the lost data. Disable BitLocker encryption before starting the recovery process.

II. How to disable BitLocker encryption?

1. Use the Control Panel to remove BitLocker encryption

Step 1: Run the computer, search for the (Control Panel) application in the “Search Box” in the lower left corner, and click on it.
