Usually I just fix it, because I think of it this way: the amount of time I'll spend fixing this is (usually) trivial compared to the amount of time they'll waste trying to fix it - if I'm someone's friend, and I can take 10 minutes out of my day to fix something that they would struggle with for an hour or two and make their life a little better, shouldn't I do it? Today you, tomorrow me.<p>That being said, I'm not particularly bombarded by these kinds of requests and I could definitely see it wearing on me if people were constantly asking me to fix their machines.
