    The DSIM.exe should fix whatever corrupt files or damaged files it finds, and the SFC scan will make sure there are no damaged or corrupt files left. [1]
    • If you see "Windows Resource Protection found corrupt files and repaired them," you may want to enter "sfc /scannow" again until you see "Windows did not find any integrity violations." [2]
    • Type "Exit" and press Enter to close the Command Prompt window.
