The main advantage of installing Windows 11 on your Steam Deck is that you will have full access to the Steam games library. This is not possible with the standard Steam OS that comes preinstalled. Therefore, you can eventually turn your Steam Deck into a fully-fledged computer or laptop. However, there are compromises. Using the OS will be more difficult without a keyboard and a mouse, and functions like suspending games are exclusive to SteamOS and won’t function on Windows.
