Yes, and they are relatively easy to edit with a .reg file instead of a 
batch file.  Below is just an example for type "Python.File" that adds "Open 
with Python3", "Edit with IDLE3", and "Open with Pythonwin3" commands to the 
right-click context menu of a .py file.  The first 3 entries are the 
original Python26 entries.  The last three were copied from them and 
modified to create the alternative context menus.  You could also create two 
.reg files that toggle the original three entries between Python 2.6 and 
Python 3.1 if you want.
