My main account has sudo rights and I type the password in whenever making root changes. I far prefer this to the windows model of admin changes only requiring a yes click.

Most stuff I install doesnt require admin anyway. Its only system updates.

On my server I do most things under a non-root account.

On my Windows machines I really don't want it to tell me what I can and cannot do. If I break it I'll fix it.

I like to actually log in as root on a terminal to do admin stuff, never got into sudo really. Old habits, you know.

I just have admin rights on my account and don't give anything I don't trust UAC permission. No installer/platform like Steam or EGS or GOG requires UAC permission if they install to a different drive, and I have Windows on its own M.2 drive, while my games go to 1 of two 2TB nvmes.

On the windows gaming machine, I let it do its own thing with UAC clickthroughs basically just notifying me when something is making system changes.

On Linux, I have a separate root password and use some combination of su, kdesu, yast, or whatever, but I never log in as root directly. I don't game that much on Linux (that machine is lacking in graphics horsepower), but things like EU4 work well enough.

When I had a windows computer I would crank the setting that requires administrator privileges way up. But the only time I actually logged into admin was to install drivers.

I just left all the stuff as it was :p.. I have 1 account I use for everything. In terms of needing a password to install software, I suppose it depends on what im installing
