Want Windows on your new Steam Machine? You can have it, but you'll have to nuke SteamOS to get it.
Valve published official Windows drivers for its Steam Machine on Tuesday, covering graphics, Wi-Fi, Bluetooth, and the SD card reader. The driver pack lands roughly one week after the $1,049 cube PC started shipping on June 30, and it brings the same OS flexibility Valve has long offered the Steam Deck.
There's one problem Valve isn't shy about: dual-boot isn't possible yet. The SteamOS installer lacks a partitioning wizard, so anyone installing Windows right now has to wipe the drive completely.
Valve confirmed the dual-boot tool is still in development and will ship with a future SteamOS update. That wait stings for early adopters who've already curated a SteamOS library. But for buyers who see the Steam Machine as a compact workstation rather than a living room console, the trade-off might be worth it.
Windows unlocks game libraries SteamOS can't touch. Riot's Vanguard anti-cheat locks "VALORANT" out of Linux entirely.
"Call of Duty" and other major multiplayer titles with kernel-level anti-cheat remain Windows-only, even with Valve's Proton translation layer running most of the Steam catalog. A Windows install also opens the door to Xbox Game Pass, the Epic Games Store, and productivity software that doesn't have Linux equivalents.
Valve is providing the drivers as-is with zero support for Windows users. The company's support page includes recovery instructions for reverting to SteamOS if something goes wrong.
The installation process has friction points. Users need to plug into Ethernet before launching the Windows installer, since Wi-Fi drivers aren't available at that stage and Microsoft requires an online product key during setup.
Booting from a Windows installer requires shutting down and tapping Escape repeatedly during startup to reach the boot menu.
Performance is another consideration. Independent testing on similar low-power hardware has shown SteamOS delivering higher gaming performance than Windows, thanks to a lighter OS footprint and tighter hardware optimization. The Steam Machine was built around SteamOS from the ground up, and that advantage shows in frame rates and power efficiency.
The driver release reinforces Valve's core positioning: the Steam Machine is a PC, not a console. As Valve wrote, "Steam Deck and Steam Machine are PCs, and other applications and OSes can be installed." That philosophy explains why Valve can't subsidize the hardware the way Sony and Microsoft do with their consoles, there's nothing stopping buyers from using the machine for anything else.
For now, the four driver packages are live on Valve's support page. Download, run the installers, and the Steam Machine becomes a fully functional Windows 11 PC.
Just don't expect to keep SteamOS alongside it. Not yet.
