Running an SFC (System File Checker) scan on Windows 11 is like giving your system a quick health check-up. It’s a built-in tool that helps you identify and replace corrupted or missing system files. To run the scan, first, open the Command Prompt as an administrator. Then, type “sfc /scannow” and hit Enter. The scan will start automatically and take some time to complete. Once finished, it will either fix the issues or give you a report on what needs attention. This simple process can help keep your computer running smoothly.
Step-by-Step Guide to Run SFC Scan Windows 11
Running an SFC scan on Windows 11 can help maintain the integrity of your system files. Follow these steps to get it done:
Step 1: Open Command Prompt as Administrator
To begin, press the Windows key and type “cmd” into the search bar, then right-click on Command Prompt and select “Run as administrator.”
Opening the Command Prompt with administrative privileges is crucial because SFC needs elevated permissions to function properly. Without this, the scan cannot access certain system files.
Step 2: Type the SFC Command
In the Command Prompt window, type “sfc /scannow” and press Enter.
Entering this command initiates the System File Checker scan. The “scannow” switch tells the utility to search for any corrupt files and attempt repairs immediately.
Step 3: Wait for the Scan to Complete
Allow the scan some time; it can take anywhere from 10 minutes to an hour, depending on your system speed and the number of files.
Patience is key here. The tool is scanning every protected system file, and while this might take a while, it’s essential for ensuring a thorough check.
Step 4: Review the Scan Results
Once the scan is finished, check the Command Prompt window for a summary of the scan results.
The results will inform you whether any corrupt files were found and if they were successfully repaired. If the scan cannot fix all issues, other troubleshooting steps might be necessary.
Step 5: Restart Your Computer
After reviewing the results, restart your computer to ensure any changes made by the SFC scan are applied.
A reboot is recommended to complete the process and allow your system to start fresh with the repairs in place.
After completing these steps, the SFC scan will have checked and possibly repaired your system files, helping to maintain the stability and performance of your Windows 11 computer.
