Yeah, basically that. I’m back at work in Windows land on a Monday morning, and pondering what sadist at Microsoft included these features. It’s not hyperbole to say that the startup repair, and the troubleshooters in settings, have never fixed an issue I’ve encountered with Windows. Not even once. Is this typical?
ETA: I’ve learned from reading the responses that the Windows troubleshooters primarily look for missing or broken drivers, and sometimes fix things just by restarting a service, so they’re useful if you have troublesome hardware.
No, however I think there might be a bit of a trap here that skews perception for some. Namely, that the automatic tools are intended to fix problems simple enough that more technical minded people would attempt the solutions it uses themselves before resorting to a troubleshooter.
