I went the opposite way and dumped windows and started telling people I had no idea how it worked anymore (Vista was a blessing, moving everything around into new places :P) which reduced my tech support to pretty much nothing.

Now whenever a novice asks for advice on what computer they should buy, I point them towards a Mac. For the most part, people just dont have problems; but when they do I tell them to go in to the genius bar so I _still_ dont have to do tech support. I offer advice, Apple handles support. Wins all round from my perspective!
