Microsoft has improved Windows over the years, but it is still far from perfect. Bugs and breakdowns are, unfortunately, still part of the Windows adventure. Whether it's an involuntary action or a tendency to tinker too much, you can quickly find yourself with a damaged or even unusable PC.
Fortunately, there is a hidden function in Windows allowing you to save your PC in just a few minutes. His name: System File Checker.
The System File Checker turns out to be a real Swiss army knife to diagnose and repair corrupted system files. This integrated function, accessible via a few simple commands, can solve a multitude of problems: unexplained crashes, applications that close suddenly, or even taskbar malfunctions.
Unlike other troubleshooting solutions that may require risky downloads or complex manipulations, SFC is an integral part of Windows. It works in depth, checks the integrity of every critical system file and restores them if necessary from Windows backup copies.
How to use System File Checker?
Contrary to popular belief, you don't need to be an IT expert to use this tool. The procedure is simple:
- Right-click on the Start menu
- Select “Terminal (Administrator)”
- Type the command “sfc /scannow”
- Let the tool do its job
The analysis is carried out automatically and informs you of the results: corrupted files detected, repairs carried out, or system in good condition. All without any risk for your computer. The process can take between 10 and 30 minutesdepending on the power of your machine and the condition of your system.
This command can also be used regularly as a preventative maintenance tool. By running it from time to time, you can detect and fix problems before they become critical. If the tool fails to fix some errors, you'll at least know that you've exhausted simple solutions before considering a complete reset.
Convincing results
User feedback is often positive. Many seemingly complex problems are resolved after a simple SFC scan: unexplained slowdowns, recurring Windows errors, update problems… The tool can sometimes even resolve performance issues by restoring essential system files that had become corrupted over time. time.
To optimize the chances of success, It is recommended to run the scan in safe mode and optionally combine SFC with other Windows diagnostic tools like DISM (Deployment Image Servicing and Management). This more conservative approach often avoids a complete system reinstallation.

- A simple “sfc /scannow” command in Terminal allows you to diagnose and repair system files
- This safe solution should be tried before any complete reinstallation of Windows
