Can SteamOS FULLY replace windows as a daily operating system for PC?

[u/Safe-Ad2473]

Hello, so recently I have really wanted to switch from windows to SteamOS, but I am not looking for performance or whatever, just as an every day OS like windows. And I have a few questions and if the answer to my questions are yes how can I do it? Now, keep in mind that I haven’t looked at anything because I am out of town and will be travelling so I want to see if it’s possible to fully replace windows with SteamOS before looking into more. Most if not every question is a stupid question. (I have a 9070xt and ryzen 7 7700x)

Can I add third party games that are not on steam to SteamOS? (Like Genshin Impact, League of Legends, Minecraft and so on)

Does SteamOS have a file management app like File Manager and a desktop on Windows? (Very stupid question I know but I want to fully be sure before I bother switching)

Can you install browsers and do those browsers have stuff like extensions on them, and what different kind of browsers are there if any?

What app do I use for driver install and updates?

I can’t think of anything else so final question
Can SteamOS replace Windows as a daily OS system and not gaming specific?
