Why Windows 10 will not succeed (and Windows will never do again)

So who could be willing to switch over?

* Private ("normal") users: People have jobs, hobbies, friends, family, TV, music, games, exercising ... you get the point. When they come home from work, do they want to deal with a new operating system? No. 15 years ago, when personal computers were the new shiny thing, they would. But today, they have smartphones (which they use more then their PCs, anyway), they have tablets and an existing computer that just works. They won't switch over.

* Private (power) users: These are the users that would spend an at-home day and be excited enough about a new operating system to try it. But are they passionate enough about Windows? Probably not. There are so many exciting pieces of technology today, Windows does, for most people, not belong to the most exciting pieces of technology anymore. Better buy a Lily camera or a Raspberry Pi. Oh, and let's not forget that power users have invested a lot of time into thorough configuration of their operating system. They don't want to lose this or need to re-configure everything.

* Business users: They want stability and reliability above everything else. Why switch to Windows 10 if your Windows 7 will still receive updates until 2020?

* Technology novices in emerging markets: People in emerging markets and developing countries often skip the PC altogether and start with mobile devices. Or they get Chromebooks, Linux, OS X.

* Mobile device users: Microsoft has been too late to the game. We all know this and Microsoft even knows themselves. This is why they focus on "reinvent[ing] productivity to empower every person and every organization on the planet to do more and achieve more" (Nadella) on any operating system.

Windows had its heyday, but it will never come back to past dominance.
