Pro tip: whenever a relative asks you to fix their computer, wipe everything and set up Linux for them. That’ll teach em.
I just tell them that I only deal with Linux and that is usually enough to dissuade.
I haven’t used Windows personally in about 15 years and professionally in about 10. I’m pretty useless on anything newer than XP. I even got my wife to switch over to a Mac Mini because at least that has a Unix-like OS and she can still do her audio work on it (in fact, better than a Windows system because their patch QA is light-years ahead of the MS “fuck it, it’ll break some systems but we’ll get that next patch Tuesday” approach).
That’s not to say that I like Apple. I just dislike their OS less than Windows.
