Oh, you mean like the 1e Wilderness Guide, Unearthed Arcana, ....

1e Splat books were the reason 2e came into being.

My parent are ~ 70 years old, and their computers are probably healthier than mine.

How?

I knew they wouldn't understand all the trade-offs involved in Internet security, so I set them up with a basic secure setup (auto-updates from MS, anti-virus, anti-spyware), and gave them 3 simple rules:

1) When you aren't using the computer - turn it off. Bad guys can't get in, or do anything to the computer, if it's not on.

2) Stay in the "well-lit" areas of the Internet. By that I mean corporate and reputable public sites - as a general rule of thumb, if they've heard about it on the news, its "well-lit".

3) Only download something when *YOU* want it, not when a site says you need it. And anytime a site says you need their special application to view video, listen to audio, or read something, they LIE.

I've also worked over the years to transition them off IE and Outlook, but that was just really icing - the basic setup and the security rules did *ALL* the heavy lifting.

Now, every so often, I'll have to do basic maintenace - renew their AV, make sure they've got all the updates, defrag their drives, etc. - but it's all relatively painless stuff. And I've never had to rebuild their computer.
