Smart app control(SAC) is a new feature in Windows 11 which makes some installations extremely slow. For example dotnet sdk takes 45 minutes to install with smart app control and under a minute without it. Reason why smart app control is so slow is that is tries to use Windows defender and it is unable to connect to it as it is disabled. At the moment it seems like it is not possible to disable the SAC from shell effectively in provisioning. Registry edit does not have immediate effect and forcing security service restarts cause forced reboot. Only disabling it manually from settings will have the desired effect.
