If your Windows 10 computer is acting up and you suspect system files might be corrupted, you can use the Deployment Imaging Service and Management Tool (DISM) to fix it. By following a few easy steps, you can repair your Windows system files and get your PC running smoothly again.
How to Use DISM to Repair Windows 10
DISM is designed to help you fix various issues with your Windows 10 installation. Let’s walk through the basic steps to use DISM effectively.
Step 1: Open Command Prompt as Administrator
First, you need to 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." This will ensure you have the necessary permissions to run the DISM commands.
Step 2: Check the Health of Your System
Next, run the command to check the health of your system files.
Type DISM /Online /Cleanup-Image /CheckHealth and press Enter. This command will quickly check if your system image has any corruption.
Step 3: Scan the Health of Your System
If the previous command finds issues, run a more thorough health scan.
Type DISM /Online /Cleanup-Image /ScanHealth and press Enter. This might take a little longer, as it will perform a deeper scan to identify any problems.
Step 4: Restore the Health of Your System
Finally, you can repair the system image if issues are found.
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This command will attempt to fix any detected corruption.
Step 5: Reboot Your Computer
After running the commands, reboot your computer to apply the changes.
Simply click on the Start menu, select the power icon, and then choose "Restart." This ensures all repairs are fully applied.
After completing these steps, your Windows 10 system should be repaired and running more efficiently.
