Step 2:- Press Enter on your keyboard to scan for corrupt or missing system files.

Step 3:- Wait for the scan to complete. If any issues are found, SFC will attempt to repair them automatically.

Step 4:- Once the SFC scan is complete, type “DISM /Online /Cleanup-Image /RestoreHealth” in the Command Prompt window without quotes.

Step 5:- Press Enter on your keyboard to scan for component store corruption.

Step 6:- Wait for the scan to complete. If any issues are found, DISM will attempt to repair them automatically.

How To Run DISM

It is important to point out that you must have a good network connection before DISM can work because it relies on Windows Updates to fix bad, corrupt, or incomplete files.

Use the shortcut keys (Windows + X) to open a menu and choose the Command Prompt (Admin) option from the list of options that appear.

If your system prompts you to confirm User Account Control, select Yes and then continue the process below.

Input the command below and then click on Enter to run the command.

DISM.exe /Online /Cleanup-image /Restorehealth


It might take more than a few minutes, so you might want to exercise patience while the command runs.
