Dell Drivers Utility for Windows 10

Hello,

What utility can I use to check for missing drivers on Dell Latitude, Precision, and OptiPlex?

I download and try the Dell SupportAssist and seems to work at the beginning but not anymore.

At first, the utility gave me a list of missing drivers and I have the option to select and install but now it just says "Online" and the only option is to "Run" which refers to install but I need to know what drivers are missing.

Thank you,Bob
