I base the opinion on decades of extensive Windows, Linux, and macOS use as well as software development on all platforms. I have a BSc in computer science. My humble and earnest opinion is that Windows is poorly designed. The thought model behind it appears to me as inconsistent, and this also manifests in how we use it. We can do better and deserve better.
If it is your opinion that this is misinformed, where would you recommend that people with opinions on Windows similar to mine could go and could inform themselves better?
Here’s another perspective: Is it more secure, less secure, or the same, if I run Windows in an enclosed VM and roll back any action which might have side effects I don’t want? I’d think that it was hard to argue anything other than it being more secure. And that reveals my point: In a better designed system it wouldn’t matter.
