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.
I would usually have issues with my wi-fi, where the connection after a reboot won’t work and the wi-fi GUI would reset itself everytime i tried. Network troubleshooter would fix it 100% every time and quite quickly, so there was no reason to actually figure out what was at fault.
