NEVER run a command you don’t know the purpose of. That being said, “sfc” stands for “System File Checker.” It is a utility that can help restore corrupted windows files.
sfc /scannow
checks your protected files and restores corrupted files from a local cache. The process can take some time and you MUST let it finish it’s entirely.In conclusion, this command is generally safe to run.

lol. Someone never followed along in a linux tutorial. /j
Well, I try to understand why something is included. I’ve run arch for years (BTW), though my current computers are running Fedora and Debian. I won’t say I know everything about Linux or even installing it or booting it, but I do know more than I would if I just followed step by step.
It’s the same for me but I didn’t always know that much about linux.
Rm stands for remove
-fr stands for the French language
/ stands for your entire system
Don’t trust random internet strangers either
So it’s removing French from your system. Sounds like a useful tool on Linux if you don’t speak French! Be sure to run as sudo though
I prefer the 'ole $sudo dd -i /dev/random -o /dev/sda
Does it also remove the French language pack?
No idea.
Also add DISM to that - if it’s corrupted it could cause you to be unable to install windows updates.
DISM /Online /Cleanup-Image /CheckHealth
It’s also possible that fixing it may require the original windows installation media matching your windows version build number - which means if you’ve since installed a major windows update there may not be an available installation iso that meets the requirement. Happened to me and I was lucky enough to coax an iso out of the windows installer download page that satisfied the repair tool (oddly enough downloading an iso using the Windows Media creation tool didn’t work, but spoofing Linux on the page to directly download an iso gave me a different iso that worked)
These are the things I do to maintain my last windows machine.
If sfc is finding anything with any regularity then your hard drive is probably failing (or maybe malware).
