was stuck in a continuous bitlocker loop, used a workaround, how do I reapply TPM as normal in RT 8

Hi,

After researching my continuous loop on startup asking for a bitlocker key on my Surface 2 Windows RT 81, I found this article

https://social.technet.microsoft.com...te-device.aspx

I followed the instructions and this allowed me to boot successfully:-

---cut---
To terminate this BitLocker recovery loop, you need to suspend BitLocker from within WinRE. To do so, use the following steps:
1.Choose the "Skip this drive" link at the bottom of the page where you are asked to enter the recovery key. You should be presented with a menu that will let you get to a command prompt (The sequence is Advanced options -> Troubleshoot -> Advanced options -> Command prompt).
2.Once you have a command prompt, use the following command to check the BitLocker status of the C: drive: •manage-bde -status c:
3.If the status is returned as locked, you'll need to use the following command to unlock it using your recovery password: •manage-bde -unlock c: -rp <your 48-digit recovery password>
4.Once the drive is unlocked you'll need to use the following command to suspend protection: • manage-bde -protectors -disable c:
5.Then exit and reboot. The computer should now successfully boot Windows. Once there, use the BitLocker control panel to resume BitLocker protection.
---cut---

My question is, how do I now put my c: drive back in the normal protected state as Windows RT does not have a Bitlocker GUI, well, it has, but it can only save the key and I am not sure of the command line actions I need to do?

My current drive status after these changes are is as follows:-

Volume C: [Windows]
[OS Volume]

Size: 54.50 GB
BitLocker Version: 2.0
Conversion Status: Used Space Only Encrypted
Percentage Encrypted: 100.0%
Encryption Method: AES 128
Protection Status: Protection Off
Lock Status: Unlocked
Identification Field: Unknown
Key Protectors:
Numerical Password
TPM

I was referred to TechNet by Microsoft answers but TechNet have not responded to me, so I would like to ask this community the same question please.

These are my other un-responded threads ;-
