They have to because of rule #1!

When my work computer got trashed by a network pushed update to Windows 10 (from 7), I took it to our helpdesk for them to fix the video drivers. They didn't know my background in managing a big IT project.
The kid says my laptop was due for a "tech refresh" meaning a new machine. I wasn't in the mood, but asked what the new computer would be. Turns out the central buy my organization did was for crippled machines. I asked him to just fix the one I had (only two years old with lots of RAM and a decent processor).
While browsing to the enterprise folder containing the correct drivers he tells me there is no Windows 10 driver for the video. He's staring at the correct install file while telling me this. I asked him to double click "there" pointing at the executable. He says it is for something else.
I eventually surrendered and took the new laptop. I never learned why he would install the correct driver. I was on our enterprise Windows 10 "golden disk" distribution.
