In this post, we will learn steps how to enable BitLocker Drive Encryption on Windows 11 operating system.
We need to enable Security Processor / TPM 2.0 (Trusted Platform Module) to use BitLocker Encryption. This is the key system requirement for Windows 11 operating system itself. We can quickly check if TPM is enabled on Windows 11 using the below steps:
Select Start > Run.(or Windows Key + R key combination)
Type tpm.msc and click OK button.
Most modern computers support TPM. We can enable TPM in UEFI firmware settings. Follow the steps to change the firmware settings to enable TPM.
Side Note: Failed Windows Update
Windows 11 update checks for PC requirements. The existing Windows 10 PC should support minimum TPM 2.0 for the Windows update to upgrade the PC to Windows 11.
Enable BitLocker Drive Encryption
Search Control Panel in the Search bar.
Choose Control Panel >> BitLocker Drive Encryption
Click Turn On BitLocker and click Yes on the Elevation prompt. We need to have Administrative privileges to enable it.
Save the Recovery key file to a location other than your PC.
Click on Next button.
In the Next Screen choose how much you want the drive to be encrypted. For existing drive choose the entire drive.
Click the Next button. In the next screen choose the Encryption mode.
For fixed hard drives the first option is best. The new mode is not compatible with older versions of Windows.
In the Next screen, choose the BitLocker System check and Click on Continue button to restart the machine.
Save all your unsaved work before hitting the Continue button.
Backup the Recovery file to some safe location other than your current PC.
After restart the entire drive would be encrypted for extra security. The process might take a while depending on the drive size.
That’s it. BitLocker is enabled on Windows 11 machine.
