Also O&O's ShutUp10 [1] which also works on Windows 11. It's not as complete as some of the scripts on Github but also only changes things known to not affect the usability of the OS. And it has a happy-clicky UI and prompts the person to make a snapshot first. I can attest to it quieting down the telemetry on W10/11 for my gaming machine. I still play certain games on Windows

These tools should be run after any big patches from Microsoft as they may change settings. ShutUp10 will show a diff of what features were reset.
