Repairing system files on Windows 11 is essential to keep your computer running smoothly. First, you’ll need to access the Command Prompt with administrative privileges. Then, use the System File Checker (SFC) and the Deployment Imaging Service and Management Tool (DISM) to scan and repair the system files. These tools work by detecting any missing or corrupted files and automatically replacing them with the correct versions.
How to Repair System Files in Windows 11
Repairing system files on Windows 11 can resolve various issues by fixing corrupted files. Here’s a simple guide to help you do it.
Step 1: Open Command Prompt as Administrator
Open the Start Menu, type “CMD,” right-click on “Command Prompt,” and select “Run as administrator.”
This step is crucial because administrative privileges are needed to run the commands that can repair system files. If you see a User Account Control prompt, click “Yes” to proceed.
Step 2: Run the System File Checker (SFC) Scan
Type the command sfc /scannow and press Enter.
The SFC tool will begin scanning your system for corrupted files. This process might take some time, so be patient. It automatically repairs any corrupted files it finds by replacing them with a cached copy.
Step 3: Use the DISM Tool
If SFC doesn’t fix the problem, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
DISM goes a step further than SFC by repairing the Windows image, which can help if the SFC tool did not resolve the issues. It’s another automated process, but it requires an internet connection to replace corrupted files from the Windows Update servers.
Step 4: Restart Your Computer
Once the scans are complete, restart your PC to apply the changes.
Restarting allows Windows to apply the repairs made during the scans. It’s like hitting the refresh button on your computer’s health, ensuring everything starts with a clean slate.
After you complete these steps, your Windows 11 system files should be repaired, and your computer should run more smoothly. You might notice better performance and fewer errors, as the corrupted system files are now fixed.
