I can't share this concern nor worry. Especially since the metrics for this is based in the millions and unfortunately the few that think as such make up not even a percent. Sad case, more should care - but I choose apathy. Microsoft will fail on other things; this is not one of them.

In 2016, that whole situation is cleared up and simpler. I remember back in 2010 - the process was not hard. You just had to ask for a Dell with the FreeDOS option (available since 2006 or so) and then your equipment would be registered differently in their system. That's how I did it when I was still doing global IT for a Fortune 500 company. We had thousands of laptops that were in that category and no hassle for warranties.

Your decisions have made your options limited. I'm of a different mind - I do not shop where I feel limited. We're just coming in from two different directions; somewhat similar concerns, different way of dealing with those concerns.

But I get the gist of what you're saying. I'd say there are some other options for you though. More modern options.

Good luck on your endeavors.
