Optional Windows features

The only two tweaks that add something instead of removing it. They switch on Windows features that are built in but off by default. Both need a restart, and neither is in Default mode.

Worth knowing

  • Windows Sandbox (-EnableWindowsSandbox, build 22483 or later) runs a clean, throwaway copy of Windows in a window, for testing software safely. It needs Windows Pro, Enterprise or Education, and virtualization turned on in your PC's firmware.
  • Windows Subsystem for Linux (-EnableWindowsSubsystemForLinux) turns on WSL and the Virtual Machine Platform, so you can install a Linux distribution from the Microsoft Store.
  • Turning them off again: untick them in the wizard. Win11Debloat then disables the same Windows features. There is no undo .reg file, because these are Windows features, not registry settings.

Every tweak, in detail

Each card shows the switch, the exact registry values from the release's .reg file, and the undo file that reverses it.
