Where it lost its way however is Microsoft actually cared about Windows, it was their flagship product after all. It was terrible in some aspects, but also excellent in some others. I particular, they took compatibility very seriously, which is far from an easy task in the wild PC ecosystem. They were also quite good in the UI/UX department. The Office suite was unmatched too, I tried a few alternative, none of them came close.
Now, they completely broke their UI/UX, and that's not just the ads, forced Copilot stuff, etc... It is pure incompetence. They still have good compatibility, but it is not as impressive of a feat as it once was, as apps today are naturally more portable because of all the abstraction layers (performance be damned, but that's another story). The traditional Office suite is still good, but they are in the process of sabotaging it with web-based apps that remove tons of features without actually simplifying anything.
