The Windows Defender Security Centre is asking me to update TPM which requires
Clear TPM. And above the
Clear TPM button, there is a text says
... Ensure you back up your data before clearing the TPM...
I was unclear about what to back up, so I googled it and found that I need to backup keys and any files have been encrypted according to the 2nd post from this thread on techpowerup.com.
I'm not entirely sure what keys need to be backed up and how. If by keys the author was referring to Credential, I have checked Credential Manager and it seems I can backup the Windows Credential but not the Web Credential.
Regarding the encrypted files, I'm not sure if he was referring to files protected by BitLocker. If that is the case, how do I find all encrypted files? I think my entire C drive was protected BitLocker but somehow the BitLocker is suspended:
