As said before I only used it as inspiration and didn’t use the script. IMHO you should at least check what the script changes before running it, to avoid being surprised by some kind of “this action has been blocked by your administrator” screen or your windows installation behaving different from what you expect (in regards to bitlocker, controlled folder access, etc.). Also note that it hasn’t been upgraded to the official 24H2 security baselines. There is also this thread which has many valuable pieces of information.
