From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I remember when SFC was first introduced, I excitedly wrote a script to invoke it remotely so I could use it on a user’s pc when they called to fix their problem. To this day I have never run that script. This was in 1998.
Its useful for fixing a Windows install after fixing a bad ram. Sometimes the utility gets corrupted so you need to fix it first.
I think it would be a great idea if some of the immutable Linux distros had a integrity checker like sfc
I think on mutable distros, or at least arch, you can run a command to reinstall all installed packages, which will verify integrity of the package files (signatures) and then ensure the files in the filesystem match package files? And I think it takes minutes at most, at least for typical setups.
I do think it's also possible to just verify integrity of all files installed from a package, but I don't remember if it required an external utility, pretty sure it's on the arch wiki under pacman/tips and tricks
When I was doing tech support I was using it a ton. I had a fleet of machines that issues with SSDs and ram
SFC has worked numerous times for me, usually for botched updates. Haven't used it in a long time after leaving tech support
I've tried using SFC multiple times and had it work zero times. One time after SFC failed to find anything wrong, I ended up fixing the machine by replacing the system file with a copy from a working machine.
