You need to update a bunch of separate things on Linux too, though. For example, apt or dnf, rpms and debs that aren’t in a repo (although Deb-get handles some of those), Flatpak, Snap, fwupd for firmware, plus language-specific things (npm, dotnet, cargo, Python, etc). At least the UIs handle a lot of it now.
WinGet, choco, scoop, &c, they all have strengths and weaknesses, which is why I had to write this: https://github.com/brianary/scripts/blob/main/Update-Everything.ps1
It’s also why I use Linux at home.
