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.
It gives a false sense of security to beginner programmers and doesn’t offer a more tailored solution that a more practiced programmer might create. This can lead to a reduction in code quality and can introduce bugs and security holes over time. If you don’t know the syntax of a language how do you know it didn’t offer you something dangerous? I have copilot at work and the only thing I actually accept its suggestions for now are writing log statements and populating argument lists. While those both still require review they are generally faster than me typing them out. Most of the rest of what it gives me is undesired: it’s either too verbose, too hard to read, or just does something else entirely.
