Configure the Surface Pro 3 device after the TPM firmware update
Turn on the Surface Pro 3, start Windows, and then log on as necessary.
Note If Windows Hello was enabled for logging on by using a PIN, this setting is no longer functional because of the TPM update process. Therefore, you must use the password that was configured for this account to log on. (See step 14 to re-enable the Windows Hello PIN options.)
Type tpm.msc, and then press Enter to open the TPM Management snap-in.
Note If TPM.msc reports that compatible TPM cannot be found or that TPM is in reduced functionality mode, restart Windows. After the restart, run TPM.msc again to verify that the state of TPM is "Ready for use."
Shut down Windows to turn off the Surface Pro 3.
Press and hold the Power+Volume Up keys to start the Surface Pro 3 into the UEFI environment. (You can release the keys after the device starts.)
To the right of Secure Boot Control, select Disabled.
Select Install all factory default keys, and then select the Windows & 3rd-party UEFI CA (Default) option.
Select Exit setup.
Select Yes when you are prompted to save the configuration and reset. The Surface Pro 3 should restart into Windows.
After Windows fully restarts, click Start.
Type manage bitlocker, and then press Enter when the Manage Bitlocker icon is selected in the Search menu.
Select Resume protection.
If your Windows Hello PIN is not working after the update (that is, the Windows logon screen reports that your PIN is no longer available because of a change in security settings), follow these steps to recover the PIN.
For Windows Hello for Business (PIN enforced by Group Policy):
Open a Command Prompt window as an administrator.
Run the following command:
Log on again by using your password. (The PIN option is not available because the Windows Hello container was removed by running the command in step 2.)
You should be prompted to create a Windows Hello PIN (as enforced by Group Policy). Follow the instructions to create a new PIN for Windows Hello.
For Windows Hello
Go to Settings > Accounts >Sign-in options.
Remove your PIN (the removal will be confirmed by using the user's password).
Click Add to create a new PIN as necessary, enter the user’s password again when you're prompted, and then follow the instructions to create a new PIN for Windows Hello.
Restart any other services that rely on TPM functionality.
