4 1 I want my system to boot straight into an application with no other UI elements. I have set the system to boot using the Custom User Interface and boot straight into the application but during the login process it shows the user name, picture, loading "dots" and background. Is there any way to just have this as a blank screen? windows-10 windows-registry group-policy share | improve this question asked Nov 13 '17 at 14:03 M murphy M murphy 21 2
