For those running in to the startmenu issue with HitmanPro.Alert installed can you try the following? Kill the user mode process of hitmanpro.alert and see if that recovers the ShellHostExperience / StartMenu. Right mouse taskbar 'Task Manager' - More details - Switch to TAB users - Click open the user - Select HitmanPro.Alert proces(ses). - Right mouse -> End Task Don't kill the service. Anyone able to host a remote support session on a system with 100% reproduction?
