Has sfc /scannow ever helped anyone?

/u/Epicsauceman111 I understand your scenario 100%, hear me out. One of the guys in the help desk team always recommends the sfc scan to the point where I want to tell him to stop wasting his time and try the next things. I still feel that way today but it is important to understand why. The way he recommends it, he is too dramatic and blows it out of proportion. I'm not in help desk, but he will often come to me when he feels that he has tried everything and can't fix it, he will walk in and say "I TRIED SFC SCAN AND IT STILL DIDN'T SOLVE THE PROBLEM" and when he explains the problem to me, I immediately tell him that it doesn't seem like an SFC issue and to try x and then it works. For example, a user clicks on a network share and it says 'denied' so he tells the user he is going to run SFC and come back or reboot and it will scan. Or someone will try to print and it shows a printer error, so he says "ok, let me run SFC and see if that solves it" instead of making sure the printer doesn't have a paper jam, is offline, etc... That's when the SFC recommendation drives me nuts. All that being said, years ago I was working with our vendor on a server issue we were having, it was very slow with most things we tried running on the server and since it was a 'new install' the vendor was on with support, but this was a new install in our building so they were working remote and I was also on the call but just there if something needed to be done locally, other than that I was just listening to the tech call via phone bridge. After the support agent tried almost everything they could think of, they recommended an SFC scan, the vendor I was working with (I've known them for a long time) was a bit annoyed since the call was already a few hours long and said 'ok, but that's not the issue' and even sent me a text stating that this was a waste of time but we obviously had to do it and I actually agreed with him, I didn't think it would be fixed with an SFC scan. Sure enough, the SFC scan fixed it. I sent a text to the vendor telling him I guess we were both wrong and via the call bridge the vendor apologized to the tech support agent for his previous comment about SFC. Having gone through that experience, I still don't assume that the issue is SFC, but I won't rule it out.
