Has Windows startup repair or a troubleshooter ever fixed your issue even once?
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.
Well, this is very specific, but the Windows 3D Builder repair tool is probably the best error fixer for 3D printing I have encountered, so at least they got that one right... I couldn't believe it when I saw it actually worked as intended lol
