For months I've been unable to successfully install updates (see attached [heavily compressed] screenshot). They're monthly roll-ups, so they render my laptop useless when applying whilst perpetually failing (15 mins trying to install after reboot, 15 mins reverting to login screen). I've tried the Windows update troubleshooter, which says it fixes "incorrect configuration" but will say that every time to no discernible benefit. I've tried manually installing from Microsoft's catalogue. SFC finds no corruption to fix; but there's one interesting thing I've spotted (see bodged path on below image for Teams, which installed itself in mid-August), but as you'll have seen I've had consistent failures since July:-
I really don't want to have to refresh my PC and lose 5 years worth of configuration, but I'm at a complete loss. I don't know if there's any log I can post that goes into further detail to help pin-point exactly why my updates are failing and what course of action I need to take (FWIW it's mostly throwing up the error code 800F0922, but occasionally I get 80246013 & 8007045B). Whether I should system restore to June and see if I can get it working or whether I should just try running the W10 installation tool that apparently still upgrades and successfully activates older Win versions.
