The whole Windows OS is an archaic joke, and so is Linux and MacOS and even FreeBSD, though the latter is currently the most advanced server OS, w/Linux leading as the desktop/embedded OS.
The way a modern OS is SUPPOSED to work, first of all, is NOT to have all the files and OS libraries sitting on a user's local disk. That's dumb. Common libraries, APIs, and utilities should be stored in the cloud. And when a user logs on to his session, he's just supposed to get runnable processes that he owns, while the file system is physically remote and/or distributed, with the illusion of only one file system being created to the user.
This is nice, however you are missing one major dynamic here.
The user.
Most computer users are stupid. And I mean really stupid. They could not tell the difference between a kernel and a piece of un-popped popcorn.
I would say that 85% of the computers users of the world are pretty much morons when it comes to computers. They just want to turn them on and have them work. And trust me, my wife is one of those. I often find it hard not to laugh when she does not want to accept some basic things (like why there are so many cords in the back of my computer, or why she can't simply put the old XP hard drive from her old HP into the new computer I built for her and have it work).
Fine, you are a power user. You use Linux (or some flavor thereof), and can't understand why most people use it. Well, I used UNIX in the late 1970's-early 1980's, and I use Linux today. And I am also aware that it is far beyond the abilities of the majority of computer users. And they do not want to learn how to use it, they just want their computer to work.
I sold computers in the early 1990's, and saw my sales increase when Win3.1 came out. Not that is was nessicarily the best GUI, but it was everywhere. And it made computers easy to use for the common people.
Here is a great example, my dad. He is close to 70, and has a laptop. He used to take it to his local computer store every year when his Norton expired, and they charged him $100 for the newest Norton and to install it. I was rather disgusted by this, and removed it, installing AVG. And every time a new version comes out, I talk my dad through upgrading it to the newest version (Tell it YES dad, say OK dad, it is fine, let it reboot dad). This is the norm for people who are not comfortable or familiar with computers.
The details you go into there may be nice, but it is so far beyond what the "regular user" is familiar with, you might as well be talking Sanskrit to them. Most computer users can't even explain the difference between Hyperthreading and Multitasking. And you want them to understand details like that? You are outta your freaking mind.
After all, there is a damned good reason that even many flavors of Linux have removed everybody's right to delete ROOT. Imagine a world where everybody has full and complete control of their computers, and deletes ROOT.
And who says innovation is good? Nobody really "innovates", they simply make changes upon what came before. And innovation is a double-edged sword. Some innovations are good, some are really-really stupid.
Because it could be very well argued that "Windows 8" is a real true innovation. Not a good one, but it is an innovation. Not all innovation is good, just as not all change is good.
