Fortunately, there is a hidden feature in Windows that can save your PC in just a few minutes. Its name: System File Checker.
The System File Checker turns out to be a real Swiss army knifeto diagnose and repair corrupted system files. This built-in feature, accessible via a few simple commands, can solve a multitude of problems: unexplained crashes, applications that close abruptly, or even malfunctions of the taskbar.
Unlike other troubleshooting solutions that may require risky downloads or complex manipulations, SFC is an integral part of Windows. It works in depth, checking the integrity of each critical system file and restoring them if necessary from Windows backups.

- Right-click on the Start menu
- Select “Terminal (Administrator)”
