Just downloaded the software/updates for an Elitedesk 800 G1 from HP Image Assistant.
Two drivers does not obey the -s switch and still pop up requesters when installing.
sp78032 Intel USB 3.0 eXtensible Host Controller Driver
sp64085 Intel Chipset Support
And yes, even the included/created install.cmd used for silent installs show the GUI when it should not. setup.exe -? does show that -s should be silent.
