Step 1 : To determine if your computer has TPM support you can check your computer model documentation or check the BIOS. In the BitLocker Drive Encryption window, look for the drive whose recovery key you’re required at the moment. Type bitlocker in Start search and from search results, pick Manage BitLocker entry.For best results your computer must be equipped with a Trusted Platform Module (TPM) chip.

While not required to use BitLocker, in order to take advantage of the full range of BitLocker protection features the following optional requirements are also necessary: Trusted Platform Module (TPM) Chip Trusted Computing Group BIOS BitLocker Drive Encryption is available only on Windows 10 Pro and Windows 10 Enterprise.

A BIOS which supports clearing of system RAM on reboot.

You might need to boot off your PC from a WinPE bootable disc and decrypt the hard drive through the command line utility – manage-bde. Sometimes things would get a bit tricky if your computer won’t start or you lost admin access to your Windows account.

Click on Turn off BitLocker to begin the decryption process.

Next, click Manage BitLocker, and on the next screen click Turn on BitLocker.

Open Windows' Control Panel, type BitLocker into the search box in the upper-right corner, and press Enter.

Data drives such as D: E: etc.) you will want to suspend BitLocker on all. If your computer has an encrypted drive used for its system other than Drive C: and/or has additional volumes encrypted (i.e. This is for computers with Drive C: system drives only. BitLocker is just temporarily disabled so the BIOS update can complete.

The task sequence will automatically suspend BitLocker and re-enable it after the BIOS update is successfully completed when necessary.

Since you don’t have a TPM, you can’t use Bitlocker with the drive-based hardware encryption.

You’re right that Bitlocker can use the hardware encryption on a drive instead of software encryption, but there are many requirements for this such as BIOS support, a TPM, a supported hard drive, etc.Use the 'Configure TPM platform validation profile for BIOS-based firmware configurations' group policy setting to configure the TPM PCR profile for computers with BIOS configurations or computers with UEFI firmware with a CSM enabled.If you enable this policy setting before turning on BitLocker you can configure the boot components that the.So my question is: Does anybody know or have a clue if or how it is possible to use Bitlocker with Windows 10, TPM 2.0 and Legacy Mode? Thanks and best regards, Sebastian On my researches I found out, that we have to install the notebooks in UEFI Mode. Unfortunately Bitlocker could not be actived on them.
