I mean, I'm not "good" at it exactly, but a lot of the old Windows XP terminology still applies (e.g. "run", "dxdiag", "device manager"), and I have a bit more intuition about computers than they do, so I can usually brute force a solution to their problems. I don't have any non-virtualized Windows computers in my house, so it is always me figuring it out, but I generally am able to figure stuff out quicker than they can.

I agree with your point though, and I've tried explaining that to them; if something is broken on your Linux box I can get you to send me a tmate URL and I can likely fix any problem you have quickly just because I am much more used to it. At some point I probably should try doing the ultimatum.

My little imaginary quote had a “good luck” at the end which made it look really flip. But, really, I think “I’m getting less and less familiar with Windows as time goes by” is more of a… gentler… way of putting the ultimatum.
