On a non-corporate Windows installation, that would just be the beginning, where I would be hunting for chipset drivers, graphics drivers, HID drivers, network drivers and any other devices I need, each needing separate hands-on installation.
Thank goodness that there's Ninite available now, otherwise all the basic apps that make up a Windows install would then still be another few hours of manual downloading and installation. And then there's restoration of your old Users directory, which is still a fraught process if you don't have a pretty good understanding of windows.
