@Technogeezer thank you for your thoughtful feedback. I would take a bit of issue with "not supported."  To my knowledge, parallels absolutely will support the product you buy from them. As for support from Microsoft - as far as we know Microsoft may already be supporting parallels (behind the scenes). What is stated in PR releases, and what is being actually done in the real world may be different.  I think we probably agree that any mission-critical situation should not dabble in any of this.  As a "PS," I think the whole TPM thing is a big mistake by Microsoft that will be slowly become less of an issue.  Just a gut feeling and I am not an expert.
