VS Code, TypeScript, C#, F#, GitHub but it doesn't count... I've heard good things about OneNote, I guess.

I would add Windows kernel to that list. Overall seems pretty solid. DirectX 12 too. Visual Studio.

Yeah GitHub/TypeScript kinda don't count. I have an ignorant question though : do people use c# or f# in a non-windows system, by choice ? Otherwise, wouldn't that be a self fulfilling need ?

Edit: typo

Yes, version 5 of the .NET platform (incl C# and F#) runs on Linux and MacOS, and people choose those languages over other languages because of their independent benefits (ie; C# has advantages over Java, and F# has advantages over Haskell/OCaml/etc).

I have not used them myself.

Bit of an aside, but TypeScript was invented at MSFT, and they still maintain it – why would it not count? (Other than not being a consumer product).

And Lean, I think, not that I know how to use it, but it seems to be respected in its world.

Windows Terminal is pretty good. VSCode is heavier than necessary but easy for everyone to use. Mostly their recent developer tools are good.

I find it useful to avoid explaining others how to set up their computer, which is indeed extremely useful ;)

Excel

Excel, Vscode

I agree! Excel is fun to play with as long as you use it on windows, I forgot. VScode I only used in college, but it seems useful. I'll update my list, paint and excel I consider good products indeed.
