How to Run SFC Scan on Windows 10: Step-by-Step Guide to Fix System Issues

Running an SFC scan on Windows 10 is straightforward. First, open Command Prompt as an administrator, then type “sfc /scannow” and press Enter. Wait for the scan to complete, which will detect and repair any corrupted system files on your computer.

How to Run SFC Scan on Windows 10

Running an SFC (System File Checker) scan is like giving your computer a health check-up. Follow these steps to scan and fix any corrupted system files in Windows 10.

Step 1: Open Command Prompt as Administrator

Press the Windows key, type “cmd,” then right-click on Command Prompt and select “Run as administrator.”

This step ensures that the command prompt has the necessary permissions to access and repair system files.

Step 2: Type the Command

In the Command Prompt window, type “sfc /scannow” and hit Enter.

By typing this command, you’re instructing Windows to scan all protected system files and replace any corrupted files with a cached copy.

Step 3: Wait for the Scan to Complete

Let the scan run. This can take anywhere from 10 to 30 minutes, depending on your system’s speed and condition.

Patience is key here; you’ll see a progress bar that will keep you updated. Don’t close the Command Prompt window until the scan is finished.

Step 4: Review the Scan Results

Once the scan completes, review the on-screen messages to see if any corrupt files were found and fixed.

This step helps you understand what issues were detected and whether they were successfully resolved.

Step 5: Restart Your Computer

Restart your computer to ensure that any changes made by the SFC scan take effect.

Rebooting will allow Windows to finalize any file repairs and ensure everything runs smoothly.

After you complete these steps, your computer will have scanned for and attempted to repair any corrupted system files. This should help resolve performance issues or errors caused by corrupted files.

Tips for Running SFC Scan on Windows 10

  • Close all other programs before running the scan to ensure it runs as efficiently as possible.
  • Regularly update your Windows operating system to minimize the occurrence of corrupted files.
