I solved the problem by logging into the PC as an Admin and then stopping the Support Assist service and setting the startup to manual. It's still available if I need it but no longer fails when a non-admin user logs in.
Hi,  I have a new Inspiron 5579. When a non-admin user logs in they get a pop-up window asking for an administrator login. Even when I put in admin credentials I still get another pop-up that says a service has failed to start.  This does not happen when an Admin user logs in to the laptop.  I have traced this to the Dell Support Assist Agent service; it won't start up for a non-Admin user.  How can I get this to work for a non-Admin user? Should I disable the Support Assist Agent and call it a day? Edit: Windows 10 Version 1709, build 16299.251.
