I’m really a bad teacher, I don’t know how to deal with people that don’t know a lot of computers …it’s a problem I have, but I’m trying to improve
The best thing you can do, like you said, is to get remote desktop/admin to works - it’s a big step to fix problems.
I’m constantly being called by my friends or family friends because of the problems with their computers. The best way I have to teach them is to right step-by-step what to do in case the same situation happens.
I can’t really recommend good tutorials, but those like ‘Introduction to computers’. He could probably learn by watching you ‘work’ since that’s how I learnt too (and by reading a lot…).
Sorry for not being more helpful
