Fixing corrupted files in Windows 11 can sometimes feel like a daunting task, but it’s usually just a series of straightforward steps. In most cases, you’ll use built-in tools like the System File Checker (SFC) or the Deployment Imaging Service and Management Tool (DISM) to identify and repair any damaged files. These utilities scan your Windows system for integrity violations and replace the corrupted files with a cached copy that is stored in a compressed folder at %WinDir%System32dllcache.
How to Fix Corrupted Files in Windows 11
In this section, we’ll dive into a detailed guide on how to fix corrupted files in Windows 11. By the end of these steps, your system should be back to its healthy self.
Step 1: Open Command Prompt as an Administrator
First, search for "Command Prompt" in the Start menu, right-click it, and choose "Run as administrator."
Running the Command Prompt as an administrator is crucial because it grants you the necessary permissions to execute repair commands. Without administrative privileges, the system might block your efforts, leaving the files unfixed.
Step 2: Use the System File Checker (SFC) Tool
Type sfc /scannow in the Command Prompt window and press Enter.
This command instructs Windows to scan all protected system files and replace any corrupted ones with a cached copy stored locally. This process might take some time, so patience is key. Keep the window open until the verification reaches 100%.
Step 3: Use the Deployment Imaging Service and Management Tool (DISM)
If SFC fails, use the command DISM /Online /Cleanup-Image /RestoreHealth.
DISM can repair the Windows image itself and should be used if SFC doesn’t solve the problem. This tool connects to Windows Update to download and replace corrupted files. Make sure you’re connected to the internet during this process.
Step 4: Restart Your Computer
Once the repair process is complete, restart your PC to apply the changes.
Restarting your computer after running these utilities helps ensure that any fixes are properly implemented. It’s like rebooting your system with a fresh start, reinforcing the changes made.
Step 5: Verify the Repair
Finally, run sfc /scannow again to ensure everything is in order.
Running the SFC command again allows you to double-check that the corrupted files were successfully restored. If the scan shows no integrity violations, your system is back to normal.
After you’ve completed these steps, your Windows 11 system should be in good shape, with any corrupted files repaired. You should notice smoother performance and fewer errors.
