Valve is working to make the Steam Deck handheld gaming computer compatible with Windows 11. Although we know for weeks that the Steam Deck runs Windows, it was not clear how Valve would support this or whether a Trusted Platform Modules option (TPM), would be available to enable Windows 11 on the Steam Deck.Valve now confirms that it is heavily focused on Windows support. In an interview with PC Gamer, Greg Coomer, a Valve Steam Deck Designer, said that there is work being done on TPM. We haven't really got that far with Windows 10 because we have been so focused on Windows 10 so far. We expect to meet that.Valve has been working with AMD to ensure that TPM is fully supported at the BIOS level and that the Steam Deck will be ready for Windows 11. Coomer says that so far, there is nothing to suggest that Windows 11 will have any problems.This is good news for Windows 11 installation on the Steam Deck, which will launch later in the year. The handheld device will come with SteamOS, which is a customized version of Linux. However, Valve will be able to support Windows installations.Why would you want Windows on the Steam Deck then? Valve is still trying to get anti-cheat games running out of the box on this handheld. It's not certain that Apex Legends or Destiny 2 will run without Windows. Valve says that they are working with BattlEye, Easy Anti-Cheat and others to ensure Proton support before launch.The Steam Deck uses Valves Proton software in order to allow a wide range of Windows games to run on it. However, anti-cheat has been a major problem for Proton in recent times. Windows support will not cause compatibility problems, but it will introduce an interface that isn't designed for a 7" screen. We won't know until then how the OS performs on the Steam Deck.
