The GamesDows repository provides a set of Windows batch scripts designed to transform a standard Windows PC into a gaming-focused system by replacing the default shell with Steam Big Picture or Playnite. The core functionality involves setting the chosen gaming interface as the default shell, creating a delayed startup script to launch Windows Explorer in the background after a short timeout (allowing exit to desktop via the gaming interface menu), and configuring scheduled tasks to restore this setup at each logon. Additionally, the scripts apply various system optimizations to reduce boot times and disable unnecessary UI elements. The implementation relies on Windows-native commands (reg, schtasks, bcdedit) and employs a self-elevating pattern to ensure the scripts run with administrator privileges. The Enable GamesDows scripts for Steam and Playnite share a common structure, differing only in the target application paths and associated file names. A complementary Disable Gamesdows script reverts all changes, restoring the default Windows Explorer shell and removing custom files and tasks. While the scripts achieve their intended goal, they contain opportunities for refactoring to reduce duplication between the Steam and Playnite variants.
