Windows 7 has been successfully installed on Valve’s Steam Deck, a device typically running on Linux. This unusual project, spearheaded by tech enthusiast Bob Pony, raises questions about the practicality and purpose of such an endeavor. While the installation is technically feasible, the operating system defaults to a portrait mode due to the Steam Deck’s screen orientation, and compatibility issues with the device’s custom AMD graphics drivers present further challenges. Despite these hurdles, Bob Pony’s experiment continues a trend of installing older Windows versions on modern devices, a pursuit driven by nostalgia and curiosity. However, given the lack of official support from Microsoft for Windows 7 and 8.1, users are advised to stick with the more stable and supported SteamOS for optimal performance on their Steam Decks. As the tech community reflects on the impending end-of-life for Windows 10, this project highlights the enduring appeal of older operating systems, even if they are no longer practical or secure for everyday use.
