The%WinDir% placeholder represents the Windows operating system folder. such as C:windows.

You will need a certain amount of time during the verification process to verify that the command Prompt window is not closed until 100% is complete, and the results of the scan are displayed after this process ends.

　　Second, after the completion of the scan generally will appear following several messages:
