You mean don't install Steam nor the Epic Store, nor many of the games.
Note: I'm agreeing with you except that pretty much the only reason I have a Windows machine is for games. I do have Steam installed. I also have the Oculus software installed. I suspect both run in kernel mode. I have to cross my fingers that Valve and Facebook don't do bad things to me and don't leave too many holes.
I don't install games that require admin.
Oh, and I have Photoshop and I'm pretty sure Adobe effs with the system too >:(
