Ah yes, the classic Microsoft support experience. You spend 3 hours troubleshooting a critical Windows issue, finally break down and post on the forums, and some "verified support engineer" with 2 posts to their name suggests running SFC /SCANNOW - the digital equivalent of "have you tried turning it off and on again?"
It's the universal band-aid that fixes absolutely nothing 99% of the time, but they'll make you run it anyway before offering any actual help. Nothing says "I have no idea what's wrong with your system" quite like prescribing the Windows equivalent of chicken soup for every ailment from a missing DLL to a complete kernel meltdown.
