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.
Once. It was a long time ago, and I don’t remember exactly what was wrong, but it did fix it. Since then I’ve run it probably 10 more times and it’s never worked again. Even when the thing that’s wrong is something that it should be able to fix, like I formatted the EFI partition, and it just needs to add its own boot loader again.
Ha! That’s one of the problems that it has failed to fix for me. I converted several machines from netboot to local boot; the EFI partition was there, but the startup repair couldn’t even handle copying the bootloader files onto it. (Or even diagnose that they were missing.)
