My grandfather decided he was determined to become tech savy a couple of years ago (meaning able to use windows), 6 months into his 'tech binge' he called me up saying that there's something wrong with the computer he's tried everthing and can't fix it. I went over and it turns out one of my younger cousins had unlocked the taskbar and moved it to the side. I promptly clicked and dragged it back into place and locked it. Turned around and my grandfather mumbled some form of thanks and proceded to not talk to me for a month after that...at least a few years on he can navigate Windows pretty well now...
