Having the same issue as reported in several other threads such as: https://www.dell.com/community/SupportAssist-for-PCs/SupportAssist-run-as-admin/m-p/7187490 We as well try to follow best practice and don't allow regular users admin permissions. This causes a problem with Support Assist because trying to run as a regular user errors out and won't install or update new drivers etc. if available. 

The solution in the linked thread (set the support assist service to run/log on as an admin user) appears to work to an extent. It will run and update drivers, etc. EXCEPT for support assist itself. If there is an update for support assist, it alerts you and if you click "yes" to run the update, support assist just closes out and nothing else happens. 

1) is there a better or more proper way to set support assist to install drivers and other  updates without changing the service logon user?

2) if changing the service logon user is still the best solution, is there another service that needs the same change to allow the support assist update process to run when prompted?
