📎 AI Summary:
The original poster is experiencing issues with BitLocker PIN recognition during startup on a Dell XPS 15 with Windows 10 Pro and TPM 1.2, despite successfully setting the PIN within Windows. They suspect a possible TPM support problem for Enhanced PINs. A colleague recommends checking TPM and BitLocker protection status via command prompts, and responses confirm that BitLocker is fully enabled with TPM and PIN protectors, but do not directly address TPM support for Enhanced PINs—leaving the main concern unresolved. Overall, the thread centers on verifying TPM capabilities for Enhanced PIN support, with some troubleshooting suggestions provided.

Hi.

I have a new Dell XPS 15 with Windows 10 Pro and a TPM 1.2 module on the board.

I have enabled Enhanced PINs via the Group Policy Editor and have set my pin using a mixture of letters, numbers and symbols. However when I restart the machine, it does not accept my entered PIN.
However, it does recognise this PIN when I am using the change Bitlocker Pin option from within Windows.

I am wondering, is there a way to find out if my TPM actually supports Enhanced PINs?

Thank you!
