How add context menu item to Windows Explorer for folders [closed]

In the registration editor (regedit.exe) find:

• Context menu for right click on folders in left panel of Windows Explorer or on background of a directory in right panel:

1. HKEY_CLASSES_ROOT\Directory\Background\shell if you are administrator
2. HKEY_CURRENT_USER\Software\Classes\directory\Background\shell if you are a normal user

• Context menu for right click on folders in right panel of Windows Explorer:

1. HKEY_CLASSES_ROOT\Directory\shell if you are administrator
2. HKEY_CURRENT_USER\Software\Classes\directory\shell if you are a normal user

• Context menu for any file:

1. HKEY_CLASSES_ROOT\*\shell if you are administrator
2. HKEY_CURRENT_USER\Software\Classes\*\shell if you are a normal user

In all cases:

1. add a new key under shell, naming it as you want to name the
   context menu item
2. add a new key inside this key, named command (mandatory name)
3. edit the default property in command to
   myprogrampath\path\path\executable.exe "%1" to pass the file path and
   name of the selected file to your custom program (for .../Directory/Background and .../directory/Background cases use %V instead of %1)
