@_elena No installation required, just run it as administrator. Some changes require a reboot and some settings "reappear" after the reboot. Just run it again. I go with recommended and limited recommended settings as a starting point before allowing stuff back on like microphone access as needed. Also after going to 24H2 my Windows installation "forgot" a couple of settings. It keeps a record of what the settings are supposed to be and asks if you want them rolled back to the previous value.
