How to Turn On or Off Auto-unlock of BitLocker Encrypted Data Drives in Windows 8


information   Information
Once a data drive has been protected with BitLocker, access to the drive is authenticated before the contents are displayed.

A fixed data drive that has been encrypted by BitLocker will either automatically be unlocked, or prompt for a smart card or password depending on how you configured it before being unlocked. Encrypted fixed data drives can be configured to automatically unlock when you sign in to Windows 8 after the operating system drive has been unlocked. To be able to automatically unlock fixed data drives, the OS drive that Windows 8 is installed on must also be encrypted by BitLocker.

When removable data drives encrypted by BitLocker are inserted into the computer, you will be prompted to provide a password or smart card. Automatic unlocking for removable data drives can be selected after the drive is encrypted without requiring the OS drive to also be encrypted by BitLocker. A removable data drive can be unlocked on any PC running Windows Server 2008 R2, Windows 7, Windows Server 2012, or Windows 8.


This tutorial will show you how to quickly turn on or off auto-unlock of BitLocker protected fixed and removable data drives in Windows 8.

Hello Talha, and welcome to Eight Forums. :)

Auto-unlock is for data drives instead of an OS drive. Your OS drive is not encrypted by BitLocker, so there is nothing to be turned off for it.

Are you having some sort of issue with your OS drive?
