Am sure as we get closer to the release 'day' that we will see something in the Insider announcements about the process to Install.
Not sure if a 'clean install' will be needed. If the OS security is that different a clean install might be a good idea.
Only small amount of discussion early in these postings about MBR and GPT. Hope that the announcement covers the recommendations for this too.
Some great tips here on finding TPM and setting it up. There was something put out that the PC Health check was now doing a better job finding TPM on laptops. PC builders will need to read their manuals, Physically inspect their motherboards and maybe order a TPM module online. There is also something about Intel PTT firmware vs TPM but not much on implementing it on specific MB.
Got plenty time to evaluate this and for Microsoft to fine tune the Insider release documentation. Concerns about individual cases and some great ideas to make sure equipment is ready.
Note: PC Health check still has some issues. Do not despair if it fails a system.
In my case, PC health check thinks I am on a 2009 Pro build when I have latest Dev, Beta, and Preview builds installed. Hopefully that will be fixed soon. So, keep checking for updates to PC health check app.
