Again, old user does not refer to the users age. Old user means a user who has previously learned the old version of the OS.
That's fine. It still does not take way from how Microsoft made a mess of the interface, given how much better it could have been and easier to use.
That is my point.
You want to make it the users fault. I want to make it Microsoft's fault. A difference of opinion.
However, I will still never allow an operating system on my computers where the provider of that OS is allowed to remove and/or block any application I want to run on it. Whether they do it or not, is irrelevant. There is nothing productive about Microsoft telling anyone what they can and cannot do with their computer.
By the way, DXDIAG is not (at least it was not last week) available in any menu option. You have to use the Windows key + R to get to it. Of course, you have to know that. Quite silly. Hopefully, one day, that gets fixed.
