    I have a Dev VM that is W10 based. I'd rather not do a complete new VM and reinstall everything (That is my nightmare situation although I assume it is possible to backup the W10 VM and restore to a clean W11 VM). I recently tried upgrading the VM to Windows 11. Of course the eligibility check failed:
    1. No support for secure boot
    2. TPM 2.0 needs to be supported and enabled
    I know these things can be done, I have a W11 VM that works just fine, in the Hardware section of config is TPM Chip (not sure where secure boot is, but it works).

    Simple question: How can I anable secure boot and the TPM chip on my W10 VM????

    Any help appreciated.

    Disappointingly, not much activity here. Regardless I have found that, if you have Parallels V16/V17 or greater (Currently @ V20), you can supposedly add a TPM chip using the Configuration --> Hardware option. See this article https://kb.parallels.com/en/122702

    Of course, life is never that easy, when I use the '+' dropdown menu to add hardware, it stops @ serial port, there is no option to add a TPM chip.

    FWIW: I have opened a support ticket with Parallels support.

    Just guessing, I am not an expert: perhaps the problem may be identified in the linked article: "Note: if a vTPM chip isn't presented in the list of devices on your Intel-based Mac to add upon clicking Hardware > +, it means your Windows virtual machine is based on Legacy BIOS. TPM chip will work with UEFI/EFI BIOS only. To check a BIOS type, follow the steps from KB 115815." From experience on about four occasions, moving things from one VM to another is a thorough headache, particularly Intel to Silicon. Backing up to OneDrive might help with some things, though not in my experience, I ended up simply reinstalling a new VM. With Parallels on Mac, I have now made a point of keeping nearly everything on the Mac side. For Microsoft applications, they almost make it painless. For other things, I have kept a screenshot list of what is there and reinstalled. My main error last time was to think I could move a Windows 11 VM from another ARM computer. Each Parallels Windows 11 VM has its own distinctive identifier. Best of luck with moving this forward.
