Why can't i put Steam to start in ADMIN mode?

[phosTR]

If i go in properties at Steam.exe and check ADM MODE and try to start Steam, i get a Steam error saying Windows will start the program in compatibility mode. If i uncheck ADMIN MODE in properties and start Steam in ADMIN MODE by right clicking, then it works.

WHY?!

You can right click on steam and "run as administrator" which should fix most permissions problesm. There's not much need to run it permanently that way as steam doesn't need those permissions aside from trying to fix certain specific issues

Bruh. First it's funny you said that about any app.
Second. Steam never was optimised client. And that become un-funny irony joke..Not sure if you mean to make it that way.

that warning is there with reason, steam actually runs pretty bad in admin mode for some people, including me

Either im become too old. Or nowadays internet become too young. Because now its too much often happen literally "X is not X but Y" and else "2x2=5" statements. I am bad at writing English. Never have issues to understand.
But looks like definition for the half of the words are changed some time ago. At least this time its German. And thats an excuse, for real. Some misunderstanding between us non-natives happened this time.

Easier way to deal with permission issues for majority of users - set steam.exe to perma Admin Run mode.
I did instead Disable Fullscreen optimisation on it only. But i often manually restart Steam in non-/Admin mode(s). Even for D/Games/Steam(Apps)/ folder(s) its installed. I suggest set permanent option for it instead.

This is and always was insurmountably STUPID advice.

Steam is built on top of a web browser. A web browser that Valve regularly and for extended periods fails to keep up-to-date and thus is riddled with security holes.
It recently updated to iirc Chromium 109 which is already half a year to a year out of date. Before that it was using Chromium 85, which was literally 4 years old; blanketed with vulnerabilities; including no less than 3 high-profile ones that allow sandbox escapes and remote code execution and have signs of exploitation in the wild.

Giving Steam long-lasting admin permission is a recipe to get malware on your system that can instantly install rootkits or bootkits with no secondary line of defense left.

Especially when you pair it with the Steam overlay, and thus said browser, being injected into game processes inheriting said admin permission.

Not to mention: Games written by porting studios doing PC-ports on what is comparatively shoe-string budget, for whom software security is the lowest of concerns feasible. And a publisher that just doesn't care.

Case in point: The entire Souls series (possibly Elden Ring as well) sharing a multiplayer network stack that for its entire lifespan an exploitable RCE in it reported multiple times to FromSoft that they never patched, until the whole thing was demonstrated in front of a live audience in the ten-thousands through a streamer.

The games themselves become a much bigger risk factor at that point as well.
