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 had a problem once when my laptop display was just black after booting. Triend everything, nothing worked. Return to OEM authorized support. They had my laptop for 4 weeks, so solution. Then just refunded the full price & retuned back the laptop.
Ubuntu LTS since then & no sick or weird issues since.
