When I finished up my custom install of Windows 7 on Sunday I was pleasantly surprised by the fact that I didn't have to install a single
driver and all of my devices/peripherals worked just fine, including my wireless mouse/keyboard, laser printer, router, everything worked as it should from the get go! I did install and update the appropriate
drivers/software for my devices but it was cool to know that hey were all recognized and functional without doing so. Easiest, most pain free installation of a windows os I've ever done!
