That feature is mostly used to manually change drivers for a device from a list of drivers already knwon to your Windows installation, or to install them from a local path you point it to. The feature will install drivers for, say, a HP printer that has been around for ages, or generic Microsoft drivers for your mouse. It won't scan nvidia.com, for example, for a new graphics card driver. Which makes sense, because what would happen is that, as in the example of that Geforce 950m product site you link in your above post (where did you get that link, btw?), that function could be broken by nvidia at any given time.Device Management offers an Update Driver feature, so why should people not use it ? What is the logic here ?
