I _do_ enjoy knowing about this ;>)  Thanks for the tip.

In the demo "context_menu.py", replace the register and unregister bits 
with the code below.  Run context_menu.py with either the --register or 
--unregister switch, as appropiate.

def DllRegisterServer():
     import _winreg
     folder_key = _winreg.CreateKey(_winreg.HKEY_CLASSES_ROOT,
                             "Folder\\shellex")
     folder_subkey = _winreg.CreateKey(folder_key, "ContextMenuHandlers")
     folder_subkey2 = _winreg.CreateKey(folder_subkey, "PythonSample")
     _winreg.SetValueEx(folder_subkey2, None, 0, _winreg.REG_SZ, 
ShellExtension._reg_clsid_)

     file_key = _winreg.CreateKey(_winreg.HKEY_CLASSES_ROOT,
                             "*\\shellex")
     file_subkey = _winreg.CreateKey(file_key, "ContextMenuHandlers")
     file_subkey2 = _winreg.CreateKey(file_subkey, "PythonSample")
     _winreg.SetValueEx(file_subkey2, None, 0, _winreg.REG_SZ, 
ShellExtension._reg_clsid_)

     print ShellExtension._reg_desc_, "registration complete."

def DllUnregisterServer():
     import _winreg
     try:
         folder_key = _winreg.DeleteKey(_winreg.HKEY_CLASSES_ROOT,
 
"Folder\\shellex\\ContextMenuHandlers\\PythonSample")
         file_key = _winreg.DeleteKey(_winreg.HKEY_CLASSES_ROOT,
 
"*\\shellex\\ContextMenuHandlers\\PythonSample")
     except WindowsError, details:
         import errno
         if details.errno != errno.ENOENT:
             raise
     print ShellExtension._reg_desc_, "unregistration complete."

Peace,
