Hello, From one of the recent updates, It seems that you need to be logged in as a local user to run all of the support assist features. I'm not sure why they did this. I hope this helps.
I installed support assist for drivers on this laptop. The support assist download successfully and works. Support assist does not however run anything but a basic hardware scan. This is very irritating. I have tried uninstalling and reinstalling. Nothing seems to help. Every other option is almost grayed out and will not allow me to start any other scans.  Here is a picture to show my Issue. I am running windows ten 64bit on an Inspiron laptop. Also, all windows updates are up to date. Update: Photo was deleted. Will post it later.  
SA, only allows hardware scan to be ran
