Here’s a step-by-step guide to running the SFC (System File Checker) command (sfc /scannow
) in Command Prompt:
Step 1: Open Command Prompt as Administrator
Press the Windows key on your keyboard or click the Start menu.
Type "cmd" or "Command Prompt" in the search bar.
Right-click on Command Prompt in the search results and select Run as administrator.
- If a User Account Control (UAC) prompt appears, click Yes to allow the program to run with administrative privileges.
Step 2: Run the SFC /Scannow Command
- In the Command Prompt window, type the following command:
sfc /scannow
- Press Enter.
Step 3: Wait for the Scan to Complete
- The System File Checker will now begin scanning your system files for corruption and missing files.
- This process may take some time (usually around 5-15 minutes), depending on your system’s speed.
Step 4: Review the Results
Once the scan is complete, you will see one of the following messages:
Windows Resource Protection did not find any integrity violations: This means no corrupted or missing system files were found.
Windows Resource Protection found corrupt files and successfully repaired them: This means the tool found issues and repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them: If this happens, the tool couldn’t repair all the issues. You can find more details in the log file by following the path:

Step 5: Restart Your Computer (Optional)
- If corrupt files were found and repaired, it’s a good idea to restart your computer to ensure all changes are applied.
