This looks like a tool that you install on each PC to maintain drivers on that particular PC model...
From the website:
"HP Support Assistant helps you maintain your PC and avoid or resolve problems using automated updates and self-help options."
I have an 840. I need to build SCCM driver packages for the 820G2, 840G2, and Zbook15 G2. I need to download all drivers for those models so they can install in a task sequence. Can I do that with Support Assistant?
