You can use BitLocker Drive Encryption to help protect your files on an entire drive. BitLocker can help block hackers from accessing the system files they rely on to discover your password, or from accessing your drive by physically removing it from your PC and installing it in a different one. You can still sign in to Windows and use your files as you normally would.
BitLocker can encrypt the drive Windows is installed on (the operating system drive) as well as fixed data drives (such as internal hard drives). You can also use BitLocker To Go to help protect all files stored on a removable data drive (such as an external hard drive or USB flash drive).
This tutorial will show you how to add or remove a Turn off BitLocker context menu for all fixed, OS, and removable drives encrypted by BitLocker for all users in Windows 7, Windows 8, and Windows 10.
