While the clean install is such a nice thing, it still means that all that we did in prior versions of Windows applies. That is, we clean install the OS but still get to find drivers and apps for our machine. It's far from automatic and nothing has changed (much) from XP to 10 in this regard.

The one thing that did change is that once you upgraded to 10 your machine is marked up at MSFT as "good to go" for 10 so no key is required. And how to skip the key is on the web too many times so I stopped writing how.
