I asked for Windows 10 questions and here’s one: “Here’s your dumb question of the month-Why is there a Windows 10?- I think part of your answer should talk about the difference between upgrade and update. Why can’t Windows make the Start Screen, Cortana and edge an update for Windows 8? (Windows 8.2,8.3, etc)
It’s certainly a valid question. Windows 10 is designed to be a desktop-focused OS unlike Windows 8 and 8.1, which focused on the touchscreen interface. Also, Windows 8 was extremely unpopular. People were furious about that missing start button and other issues. It was important for Microsoft to distance themselves from 8, much the same way they ran away from Vista.
Also, by creating an OS that both Windows 7 and 8 could be upgraded to, they were able to get more users on the same operating system.
Ten is also a nice round number. There’s a possibility that this might be the last numbered Windows OS as Microsoft switches to a different model of distributing Windows.
