Could you elaborate? Setting us back by a decade seems like a pretty bold claim. And I say this as someone that, on balance, despises the Microsoft of the past (for monopolistic behaviour) and present (for spyware and normalizing hardware lockdown).
It's definitely a bold claim and one people don't want to discuss. Bar the points you mentioned, mainly that they seriously stunted the rise of the Internet and world wide web. When it did take off, due to market share and mindset, they actively locked people into their vision of it. People are still, right now in 2018, trying to escape some of their grasp. There's still ActiveX out there. Plus the damage they did to Java for example.
