Running an SFC scan in Windows 11 is a straightforward process that helps you identify and fix corrupted system files. First, you need to open the Command Prompt as an administrator. Then, you type "sfc /scannow" and press Enter. The system file checker will then scan your system and automatically repair any corrupted files it finds.
How to Run SFC Scan Windows 11
Running an SFC scan in Windows 11 can help fix corrupted system files that might be causing issues. Follow these simple steps to complete the scan.
Step 1: Open Command Prompt as an Administrator
First, you need to open the Command Prompt with administrative privileges.
To do this, click the Start button and type "cmd". Right-click on "Command Prompt" and select "Run as administrator". This will open a Command Prompt window with elevated privileges, allowing the SFC command to make system changes.
Step 2: Confirm the User Account Control (UAC) Prompt
Next, a User Account Control (UAC) prompt will appear.
Click "Yes" to confirm that you want to allow the Command Prompt to make changes to your device. This step ensures that you’re authorized to run commands that modify system files.
Step 3: Type the SFC Command
Now, in the Command Prompt window, type "sfc /scannow" and press Enter.
This command instructs the System File Checker (SFC) to scan your entire system for corrupted files. Make sure you type the command exactly as shown, including the space between "sfc" and "/scannow".
Step 4: Wait for the Scan to Complete
The scan might take some time, so be patient.
During this phase, the system file checker will go through your system files and repair any that are corrupted. You don’t need to do anything while this process is running, just wait for it to finish.
Step 5: Review the Scan Results
After the scan completes, you’ll see a message indicating the results.
The Command Prompt will inform you if any corrupted files were found and if they were successfully repaired. If issues were detected but not fixed, you might need to take additional steps, such as running the scan again in Safe Mode.
After you complete these steps, your system will have scanned and attempted to repair any corrupted files. If the scan was successful, your system should run more smoothly.
Tips for How to Run SFC Scan Windows 11
- Ensure your computer is plugged in: The scan can take a while, and you don’t want your PC to shut down mid-scan.
- Close other programs: Running other programs can slow down the scan and might interfere with its progress.
- Run the scan in Safe Mode: If the scan fails, try running it in Safe Mode for a cleaner environment.
- Use DISM if SFC fails: If SFC can’t fix the problems, the Deployment Imaging Service and Management Tool (DISM) might help.
