4. Then go to the HKEY_CLASSES_ROOT, WinRAR.ZIP, shell, open and command
5. Next right-Click the Command key and choose Export from the context menu
6. Then Windows will ask you to specify a file name and a location to save the copy
7. Right-Click the registry file and choose Open with Notepad
8. Then replace the command Runas in place Open
