Only a very few are willing to use the WDAC wizard, can modify the policy, convert it to binary and then copy-pasta it to CodeIntegrity folder. The vast majority of home users, even hardcore security geeks, are not going to spend a few days reading Microsoft learn docs. WDAC has a usability problem. Home users aren't going to figure out all the scripts and utilities that Microsoft has to supply professional sysadmins in order to get even them to use WDAC - which most do not despite Microsoft having to create all those helper utilities. That is why virtually nobody uses WDAC.
Or did you write a guide or create a GUI that makes it all a one or two-step procedure for home users?
