What open source programs do you recommend for Windows? (Windows exclusive or not) - Divisions by zero

I am and all my life have been a Linux user, I have nothing against Windows or MacOS, I just like Linux, and lately I have been experimenting with Windows in a virtual machine and I don’t really know much open source software there apart from the one that is cross-platform. like Firefox or Joplin. At the moment I know: Flow Launcher [https://www.flowlauncher.com/]: It’s a typical rofi style launcher, although I’m not a TWM user I like to just press super and type the first letters of the program I’m looking for to open it. Lively Wallpaper [https://www.rocksdanister.com/lively/]: A program to have animated wallpapers, in the style of Wallpaper Engine.
