Fixing corrupted files in Windows 10 might sound like an overwhelming task, but it’s actually quite manageable. By using built-in tools like the System File Checker (SFC) or the Deployment Imaging Service and Management Tool (DISM), you can often resolve these issues in just a few steps. These tools scan your computer for corrupted files and can replace or repair them automatically.
How to Fix Corrupted Files Windows 10
Let’s walk through how to fix corrupted files in Windows 10 using a couple of methods to ensure your system runs smoothly.
Step 1: Open Command Prompt as Administrator
First, access 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’. This step is crucial because you’ll need admin rights to execute system-level commands. It’s the key to unlocking the tools you’ll be using.
Step 2: Run System File Checker (SFC)
In the Command Prompt window, type sfc /scannow
and hit Enter.
This command will instruct Windows to scan all protected system files and replace corrupted files with a cached copy. It might take some time, so be patient. Remember, patience is a virtue!
Step 3: Use DISM if SFC Fails
If SFC doesn’t fix the problem, type DISM /Online /Cleanup-Image /RestoreHealth
and press Enter.
The DISM tool checks the health of your Windows image and repairs any issues it finds. It’s like a doctor’s check-up for your system, ensuring everything is as it should be. This might take a while, so go grab a coffee or stretch your legs while you wait.
Step 4: Restart Your Computer
After running these tools, restart your computer.
A simple restart allows Windows to apply changes from the repairs. Think of it as a fresh start for your system. It ensures that any changes made by SFC or DISM take full effect.
Step 5: Verify File Integrity
Once your computer has restarted, use the SFC tool again to verify that all issues are resolved.
Re-running the sfc /scannow
command checks whether the earlier repairs were successful. It’s like double-checking your homework before turning it in.
After following these steps, your Windows 10 should be in better shape. Corrupted files should be repaired, and your system should run more smoothly.
