Nearly all of these "clean up" scripts are a horrendous idea to run on your machine, I see right at the top that this script disables SmartScreen, a service that absolutely should not be disabled unless you want your machine to get owned.
It then proceeds to set your current network as Private (aka "open all the ports") regardless of which network you're connected to - hope you're at home! Other changes are completely superfluous, like disabling "3D Objects" which has already been disabled in the latest Windows version
