BitLocker is the name for the disk encryption that comes with some editions of Microsoft’s Windows 10 operating system. Windows 10 Home does not come with BitLocker encryption because Microsoft keeps it reserved for the business and education editions, but you can find it starting from Windows 10 Pro. If you have a computer that runs on Windows 10 Home and you want to it have BitLocker encryption, you’ll need to upgrade the computer to Windows 10 Pro; there’s no way you can add the encryption feature by itself.
Computers equipped with BitLocker have a handy advantage with preventing the theft or exposure of information that you have stored on your drives. This includes if your computer has been lost or stolen, as when someone else tries to use the computer, they won’t be able to access the information that was being protected by BitLocker on the drive/drives.
While computers that have BitLocker encryption currently operating have a very low chance of something going wrong, one of the reasons Microsoft might not offer it to Home users just yet is because it can be a double-edged sword and prevent you from getting access to your drives if something goes wrong. Thus, it is currently best reserved for people who have extremely sensitive data such as businesses transactions and information.
The following tutorial demonstrates how to deny write access to removable drives not protected by BitLocker disk encryption.
