How to Unlock an OS Drive Encrypted by BitLocker in Windows 10
BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers.
When you turn on BitLocker for an OS drive, you can choose to unlock the drive at startup with a password, USB flash drive, PIN (with TPM), or automatically unlock.
If you chose to unlock the OS drive with a password, PIN, or USB flash drive and forgot or lost them, then you can still unlock the OS drive with its BitLocker recovery key.
This tutorial will show you different ways on how to unlock an operating system (OS) drive encrypted by BitLocker in Windows 10.
