If you’re dealing with a sluggish computer or mysterious errors, corrupted files might be the culprit. To check for corrupted files on Windows 10, you can use built-in tools like the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM). These tools will scan and repair corrupted files, ensuring your system runs smoothly.
Step-by-Step Tutorial for Checking for Corrupted Files on Windows 10
The following steps will guide you through using SFC and DISM to check and repair corrupted files on your Windows 10 computer.
Step 1: Open Command Prompt as Administrator
First, you need to access the Command Prompt with administrative privileges.
Right-click the Start menu and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)." This ensures that you have the necessary permissions to run the commands.
Step 2: Run the System File Checker (SFC) Command
Type sfc /scannow and press Enter to initiate the scan.
The SFC tool will scan all protected system files and replace corrupted files with a cached copy. This process might take several minutes, so be patient.
Step 3: Review the Results
Once the scan is complete, review the results shown in the Command Prompt.
The SFC tool will provide messages indicating whether it found and fixed any issues. If it couldn’t repair some files, you will need to run the DISM tool.
Step 4: Run the DISM Command
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter to start the repair.
The DISM tool will scan the Windows image for any corruption and attempt to repair it. This process might take up to 20 minutes, depending on the level of corruption and your system’s speed.
Step 5: Restart Your Computer
After the DISM tool completes the scan, restart your computer to apply the changes.
Restarting ensures that any repairs made by SFC or DISM take effect, returning your system to optimal performance.
Once you’ve completed the steps, your computer should run more smoothly, with any corrupted files repaired or replaced. If issues persist, further troubleshooting may be necessary.
Tips for Checking for Corrupted Files on Windows 10
- Regularly run SFC and DISM: Making these scans part of your maintenance routine can help keep your operating system in top shape.
- Backup before scanning: Although these tools are safe, backing up important data is always a good precaution.
- Run DISM before SFC if issues persist: Sometimes DISM can fix underlying issues that SFC cannot.
- Keep your system updated: Ensure your Windows 10 is up to date to avoid common file corruption scenarios.
- Use antivirus software: Regular scans with an antivirus program can prevent file corruption caused by malware.
