The Steam Deck operates on Linux, which limits access to certain games and services that require Windows, such as PC Game Pass titles and multiplayer games with anti-cheat software. Users can integrate Windows 11 into their Steam Deck by creating a portable version on a USB-C SSD. Recommended SSD options include the Crucial X6 2 TB SSD or a Genki SavePoint SSD enclosure for M.2 2230-size SSDs. To download Windows 11, users should visit Microsoft's website and select the appropriate ISO file. Creating a bootable drive involves using Rufus to set up the SSD with Windows 11. After downloading Valve's official drivers for the Steam Deck, users can boot into Windows by connecting the SSD and selecting it from the drive selector screen. Adjustments may be needed for display settings, and installing the Steam Deck drivers is recommended for optimal functionality. Once set up, users can access a wider range of PC gaming experiences, including the Xbox app for PC Game Pass titles.
