My HTPC is on windows 11, set to auto log-in and launch steam big picture. Disabled as much of the Microsoft BS as I can, including the nags to use Onedrive or sub to Office 365 every major update.
Using Unified Remote to control things with my phone and also Parsec/Moonlight for game streaming to other devices.
My media is served from my Unraid server to my devices both locally and remotely.
