The only Microsoft products I’ve actively heard people desire within the last 5 years are VSCode and Excel. Microsoft have so severely damaged their brand that they’ve finally shed the image of oddly gray Dell midtowers running XP on Pentium 4.
Somewhat more niche, I'd also add Access to the list. There is worryingly little development going on these days, but after all these decades there is no other product who came even remotely close to its quality. For quick local RDB stuff and some RAD, nothing is as quick and reliable. I still use it for all of my personal collection tracking, data modeling and prototyping for hobby projects, etc. The speed at which I can set up and adjust is unreal. I appreciate that LibreOffice are giving it a try with Base, but every time I try it, it takes me about 2 minutes until I find a basic, essential feature that's severely broken. (I guess I know which project I should start contributing to if I ever got into the mindset of doing some open-source work.)
Jupyter also has a janky execution model. It doesn’t track dependencies so you have to be very careful in how you separate cells from one another and just running the whole notebook every time seems kind of pointless vs just writing a pure Python script.
But as a professional, it has no further use.
[0]: Please tell me how I add a new paragraph style in Docs?
World has had ctrl+b for bold forever, so people can start to use it and then upgrade to styles when they run into the limitations. Alternatively someone knowledgable could set Word to only allow a selection of styles.
Open and Libreoffice has had style support since forever. Its only docs that kneecaps its users learning journey like that.
