What is BitLocker and Why is it Used?

BitLocker is a full-disk encryption feature developed by Microsoft for Windows operating systems. It’s designed to protect data by encrypting the entire drive, ensuring that unauthorized users cannot access your files even if they have physical possession of the hardware. BitLocker is commonly used in both personal and enterprise environments to safeguard sensitive information.

Why Would You Want to 關閉 BitLocker?

How to Check if BitLocker is Enabled?

Before you proceed to 關閉 BitLocker, it’s essential to confirm whether it’s currently enabled on your system. Here’s how you can check:

1. Open the Control Panel and navigate to "System and Security."
2. Select "BitLocker Drive Encryption."
3. Check the status of your drives. If BitLocker is enabled, you’ll see an "On" status next to the drive.
