Haven't used Windows in a decade, but third party apps on Windows don't even have the framework for some sort of package management, do they? At least with snap/flatpak/AUR/PPA you got an aggregated updating interface and optionally sandboxing for snaps and flatpaks. I think, something like Appimages are the better fitting equivalent to Window's normalized madness, no?
