The Steam Deck ships with SteamOS 3.0, an in-house built modified Arch Linux distribution, but Valve is continuing to remind everyone that the handheld is a PC and not a locked down console. Today, Valve began offering Windows drivers for its newly-released hardware, giving owners another choice when it comes to operating systems.
GPU, WiFi, and Bluetooth drivers for Windows are now available, which should be installed for optimal performance and stability on the Steam Deck. Those interested in jumping over can check out Valve"s helpful Steam Deck - Windows Resources page here. There are some caveats to keep in mind though.
Only Windows 10 is what"s supported for now, not 11. "We are preparing a BIOS update that enables fTPM, which is required to install Windows 11," adds Valve. Another down side is not being able to dual-boot with SteamOS and Windows just yet, with the company still working on the feature. Also, Windows audio drivers are still in the works for the handheld, so the speakers and 3.5mm audio port will not provide any audio. The USB-C and Bluetooth can be used for gaining audio in the meantime on Windows.
Other than the resources page, Valve won"t be providing additional support for getting Windows running on the Steam Deck. Those that may want to switch back to the original SteamOS 3.0 operating system can do so by following the recovery instructions on this support page.
