Not sure if it qualifies as a "product", but .NET is (these days) uncharacteristic for Microsoft as well. It's community-driven, very active, and quite liked by the people who use it.

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.)

The last company I worked for had copilot pretty well integrated into M365/Sharepoint/Teams. It didn't really help me get more work done but it was pretty clutch at finding information. "What meeting did we discuss such and such for X project?" And it'd get me the meeting with the notes and recording. "Which SharePoint site do the docs for that live in?" Etc. That was about all it was good for though.

I work in big financials. Everything used to be built on Excel. A lot still is but Python/Jupyterhub or custom applications has taken over a lot of the complex stuff. Excel isn't really essential any more.

Not sure they count as “products” in this context, but TypeScript and Playwright are still nice.

Windows is still the king for gaming. Word is better than Google Docs for anything but the absolute basics[0].

But as a professional, it has no further use.

[0]: Please tell me how I add a new paragraph style in Docs?

this is true only on HN. in reality, if you wanted a job where you did not use microsoft products you’d probably have to get a wrench and start doing plumbing work :)
