How to Check for Corrupt Files in Windows 10
To check for corrupt files in Windows 10, open the Command Prompt as an administrator, then use the System File Checker tool by typing "sfc /scannow" and hitting Enter. This process scans your system files and repairs any corrupt files it finds. It’s a straightforward process, but it can take some time to complete.
Step-by-Step Tutorial on How to Check for Corrupt Files in Windows 10
Let’s dive into the steps for checking and repairing corrupt files on your Windows 10 device. Follow these steps carefully to ensure a smooth process.
Step 1: Open the Command Prompt as Administrator
First, you need to access the Command Prompt with administrative privileges.
Right-click the Start button and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)." You should see a black window pop up, indicating that you’re ready to type commands.
Step 2: Run the System File Checker Tool
Type "sfc /scannow" into the Command Prompt window and press Enter.
This command starts the System File Checker tool, which scans your system files for corruption and attempts to repair them. The scanning process can take some time, so be patient and let it run its course.
Step 3: Wait for the Scan to Complete
Allow the System File Checker to complete its scan. This may take up to several minutes.
During the scan, the tool will automatically fix any corrupt files it finds. You will see a progress bar that gives you an idea of how much longer it will take.
Step 4: Review the Results
After the scan completes, review the results displayed in the Command Prompt.
If corrupt files were found and repaired, the Command Prompt would inform you of the actions taken. If no corrupt files were found, it would say so as well.
Step 5: Restart Your Computer
For the repairs to take full effect, restart your computer.
Restarting ensures that all changes made by the System File Checker are implemented properly. Once your system reboots, it should be running more smoothly.
After completing these steps, you should notice an improvement in your system’s performance if corrupt files were the issue.
Tips for Checking for Corrupt Files in Windows 10
- Use a stable power source: Ensure your computer is plugged in to avoid interruptions during the scan.
- Close other programs: Exit all other programs to allow the System File Checker to work more efficiently.
- Regular scans: Run the System File Checker periodically to keep your system in good shape.
- Backup important files: Always back up important data before running system scans or repairs.
- Follow up with DISM: If SFC doesn’t fix the issue, the Deployment Imaging Service and Management Tool (DISM) can be a more advanced option to repair the Windows image.
