Valve have gathered up some crucial Windows drivers for the Steam Deck, improving performance for those who want to ditch the default SteamOS and replace it with Windows 10. GPU, Wi-Fi and Bluetooth drivers are all available from Steam Support, so early Deck adopters looking for a change can get the requisite downloads all in one place.
These drivers come with caveats, mind. Audio drivers are still working in progress, so only USB-C, 3.5mm, or Bluetooth headphones can output sound on Windows, and Valve’s post explains that dual-booting support still is not ready yet. Installing Windows, then, is an all-or-nothing switch that involves wiping SteamOS entirely.
You’ll also need to use a USB-C hub with an Ethernet port to activate Windows during setup, as the Wi-Fi driver can only be installed after Windows is installed. It’ll need to be Windows 10, too, as Windows 11 isn’t supported yet either (though Windows 11’s gaming features aren’t exactly essential). Oh, and Valve are “unfortunately unable to offer ‘Windows on Deck’ support”, so if it goes wrong you’re on your own unless you switch back to SteamOS.
That’s a lot of bad news for what is ultimately a step forward, so here’s some good. Firstly, installing Windows in the first place remains quite simple: you just need to create USB installation media and force the Steam Deck to boot from it, much like you might when installing Windows on a desktop PC. And while it was possible to get Windows running on the Deck without these drivers, they should make the whole experience a lot smoother and faster.
Valve have also released Steam Deck recovery instructions, which will re-install SteamOS and thus offer a route back if you decide Windows was not the right choice. I performed this very process while I was testing for our Steam Deck review, and it’s easy enough.
Pre-ordered Steam Decks are still in the early stages of getting shipped out, so hopefully by the time most orders are fulfilled it’ll be upgraded with dual-booting and even better Windows driver support. In the meantime, existing Deck owners can either try their luck with Windows 10, or look into other methods of getting non-Steam games running on SteamOS. This guide on how to install the Epic Games Launcher on the Steam Deck can help with that.
