Depends on the level of hands off administration you want to do.
1) For geeks and mostly computer savvy folks an install of competent Anti-Virus, Firewall, and Anti-Malware Suite and about an hour of teaching them about safe computer usage practices will suffice. The percentage of people this applies to is still quite small.
2) For the non savvy user, the options are somewhat limited. The above will NOT work. It will only make you and them frustrated in the long run.
a) If you have the money and option, go with an iOS device - computer or tablet. This won't completely remove your IT duties for them, but it will drastically lessen them after they get over the initial learning curve.
b) In some cases, installing a distro of Linux will work. This is mainly for users who only want to do email and browser things and are not looking to do anything fancy such videos and social sites. It's not that the various flavors of Linux can't do that stuff, it just requires special attention to get it to work. But usually after it is setup it doesn't need to be messed with.
c) For the most typical case, ie the user who wants to use their existing computer, about the only option left is to quarantine them from the computer configuration. Couple ways to do this: either Virtual machine that restores the startup state on each restart, or a tool like Deep Freeze that effectively whitelists executables on the existing computer and blacklists any configuration/installation changes. For my ailing father, this was the only option, his mind was not up to doing anything else. He just wanted to look at pictures in the computer and a little bit of Internet stuff.
In all cases, a remote administration tool will help out when they have further questions. Team Viewer happens to be my particular poison in this area.
