What Is System File Checker (SFC)?

TechDogs Avatar

As a Windows user, you know that sometimes things can go wrong. Your favorite app constantly crashes, or you may get an error when opening a file. If that happens, don't panic! The good news is that there's probably something you can do about it, even if this is the first time anyone else can help. The bad news? Well, that's where the System File Checker (SFC) comes in handy. System File Checker, or SFC for short, is a utility built into Windows 10 that helps administrators check for file corruption and repair registry data. It's a feature of modern operating systems, including Windows 10, Windows 8, and Windows 7. SFC can scan your system files and repair or replace any corrupted or missing files with a healthy copy from the source. The tool identifies which files are corrupt or absent in the system. It replaces them with an updated version of the corrupted file or a good copy from another location on your computer where the same file exists. System File Checker compares the system's current files against a known good set of files. It also allows users to choose a specific drive or directory to examine for issues. If it finds any problems, System File Checker will attempt to repair them. Ever had a computer freeze up on you? Did it happen at the worst possible time, like you're trying to finish a report or just about to check out your hotel room? Well, here is some excellent news: an app that can fix all your problems! It's called "System File Checker," and it's free! You download it from the Microsoft website, then run it. If System File Checker finds any errors or issues with the system files, it'll let you know so you can fix them immediately.
