How to Check for Corrupted Files in Windows 10
Checking for corrupted files in Windows 10 might sound like a daunting task, but it’s quite straightforward. You’ll use built-in tools like the System File Checker (SFC) and the Deployment Imaging Service and Management Tool (DISM) to scan and fix these issues. Here’s a quick guide to walk you through the process step-by-step.
How to Check for Corrupted Files in Windows 10
The following steps will help you identify and fix corrupted files in Windows 10. By following these instructions, you can ensure your system runs smoothly and efficiently.
Step 1: Open Command Prompt as Administrator
To start, 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."
Step 2: Run the System File Checker (SFC) Scan
Type "sfc /scannow" and press Enter.
This command will scan all protected system files and replace corrupted ones with a cached copy located in a compressed folder at %WinDir%System32dllcache.
Step 3: Wait for the Scan to Complete
The scan might take some time, so be patient.
Depending on your system’s configuration, it can take anywhere from several minutes to an hour. During this time, you might notice your system running a bit slower than usual.
Step 4: Review the Scan Results
After the scan completes, you’ll see one of the following messages: "Windows Resource Protection did not find any integrity violations," "Windows Resource Protection found corrupt files and successfully repaired them," or "Windows Resource Protection found corrupt files but was unable to fix some of them."
Based on the message, you may need to take additional steps if some files couldn’t be fixed.
Step 5: Use DISM Tool if Necessary
If SFC couldn’t fix some files, run the DISM tool.
Type "DISM /Online /Cleanup-Image /RestoreHealth" in the Command Prompt and press Enter. This tool will use Windows Update to provide the files required to fix corruptions.
After completing these steps, your system should be free of corrupted files, or you will be informed if further actions are needed.
