How to Repair Corrupted Windows Files (SFC Scan)

 If your Windows computer is crashing, freezing, or showing strange error messages, some of your core system files might be corrupted or missing. You do not need to reinstall the entire operating system to fix this. You can easily repair your PC using the built-in System File Checker (SFC) tool.

Here is how to run an automatic scan and repair:

Step 1: Open Command Prompt as Administrator To use this tool, you must open the command line with full administrative rights.

1. Click the Start button (Windows icon) on your taskbar.

2. Type cmd into the search bar.

3. On the right side of the search results, click on Run as administrator. Click "Yes" if Windows asks for permission.

Step 2: Run the SFC Command A black window with white text will appear on your screen.

1. Type the following command exactly as shown (notice the space before the slash): sfc /scannow

2. Press Enter on your keyboard.

3. The tool will begin scanning your entire system for corrupted files. This process usually takes 10 to 15 minutes. Do not close the window until the verification reaches 100%.

Once the scan is complete, Windows will automatically replace any damaged files it found.

Restart your computer to apply the final repairs. Your system should now run smoothly without random errors.
