How to SFC Scan Windows 10
Running an SFC scan on Windows 10 is a straightforward process that can help fix system file issues. By following a few simple steps, you can use the System File Checker (SFC) tool to scan for and repair corrupted or missing system files on your computer. This is a quick and effective way to resolve various system issues without needing advanced technical knowledge.
How to SFC Scan Windows 10
The steps below will guide you through the process of running an SFC scan on your Windows 10 computer. This will help you identify and repair any corrupted system files that might be causing problems.
Step 1: Open Command Prompt as Administrator
First, you need to open Command Prompt with administrative privileges.
To do this, type "cmd" in the Windows search bar, right-click on "Command Prompt," and select "Run as administrator." This will ensure you have the necessary permissions to run the SFC scan.
Step 2: Type the SFC Command
Next, you’ll need to type the SFC command into the Command Prompt window.
Type sfc /scannow and press Enter. This command tells the System File Checker to begin scanning your system for any corrupted or missing files.
Step 3: Wait for the Scan to Complete
The SFC scan will now begin, and you will need to wait for it to complete.
This process can take some time, depending on the speed of your computer and the size of your hard drive. Be patient and avoid using your computer for other tasks during the scan.
Step 4: Review the Scan Results
Once the scan is complete, review the results displayed in the Command Prompt window.
The System File Checker will inform you if it found any issues and whether it was able to repair them. If it found and fixed problems, you might need to restart your computer for the changes to take effect.
Step 5: Take Further Action if Necessary
If the SFC scan found issues it couldn’t fix, you might need to take additional steps.
In such cases, you can use the Deployment Imaging Service and Management Tool (DISM) to repair the system image. Afterward, run the SFC scan again to ensure all issues are resolved.
After completing the SFC scan, your computer will be checked for corrupted or missing system files, and any issues found will be repaired. This can help improve your computer’s performance and stability.
