To go back to your first post in this thread:
The Windows 10 EULA states that by using certain "software and services" you agree to be bound by certain other terms. However, the MSA starts with the sentence "These terms (“Terms”) cover the use of those Microsoft’s consumer products, websites, and services listed
here (the “Services”)."
So the Windows 10 EULA binds you to the MSA, but the MSA
explicitly limits its own scope to a fixed subset of MS services. That means any service not listed in the "Covered Services" section of the MSA is
explicitly not covered by the MSA. The MSA only applies to your use of those services. End of story. There's not even any legalese to wade through there. If MS want to mess with your use of Windows, they can only do it within the limits of those listed services (until/unless they update the covered services list, obviously).
Of course, there may be other parts of the EULA or other agreements that they can screw you under, but the hype over MSA is massively overblown.
