    Apologies if this has been covered elsewhere in the forum - I could not find anything. I installed, configured and activated a new install of Win11 Pro that had TPM installed. I am in the habit of clean re-installing my Mac frequently and thus having to re-install Parallels and my VM's. To do this, I keep a copy of the Win11 VM offline and simply move it back to the Parallels folder and open it to restart. Latest time I did this, Parallels is complaining that Windows is configured to start with TPM but it cannot read any TPM info:

    I can see there is no TPM chip in the VM config. My question is how can I restore the TPM chip to stop this window appearing. The Win11 VM is reporting it is activated.
