You can now install Windows on Steam Machine — but it wipes SteamOS completely
Valve has released official Windows drivers for the Steam Machine, letting buyers replace SteamOS with Microsoft's OS — but only by wiping the console's built-in operating system entirely. The driver package covers graphics, Wi-Fi, Bluetooth, and the SD card reader. For a device priced between $1,049 (512GB) and $1,349 (2TB), that's a significant compromise.
The catch
The Steam Machine hardware is technically capable of dual-boot, just like the Steam Deck. The problem is SteamOS doesn't yet include a dual-boot wizard to make it work cleanly. Until that feature ships — Valve says it's coming in a future SteamOS update, but hasn't given a timeline — anyone who wants Windows has to give up SteamOS completely. Valve is direct about its support limits:
> "We provide these resources as-is and are unfortunately not able to offer support for Windows on Steam hardware. If you run into trouble and need a way to get back to the default SteamOS, follow the recovery instructions."
The installation process itself adds friction. To access the Windows boot menu, you have to power off the device and restart it while holding Escape. Entering a Windows product key requires an internet connection, but Wi-Fi drivers aren't present at the start of setup — so you'll need a wired Ethernet connection to get through the initial install.
Why this matters
The Steam Machine was positioned as a living-room gaming console running Valve's optimized SteamOS. The Windows option is framed as openness, but it exposes a familiar problem: anti-cheat software from games like those using BattlEye or Easy Anti-Cheat still has gaps on Linux, pushing competitive gamers toward Windows anyway. Choosing Windows fixes that — but at the cost of the seamless SteamOS experience Valve built the device around.
At $1,049 to $1,349, the Steam Machine sits well above the PS5 ($499) and competes with high-end mini-PCs. Its hardware is genuinely capable — a semi-custom 6-core AMD Zen 4 CPU clocked up to 4.8 GHz, AMD RDNA3 graphics with 28 compute units, 16GB DDR5, and 8GB GDDR6 VRAM — but the OS flexibility most buyers expected isn't here yet.
Valve's promise of an official dual-boot wizard, per VideoCardz, remains without a release date. Windows Central notes this mirrors the same dual-boot gap Steam Deck users experienced — that took years to close properly.
