Trying to translate the latter to Windows ...
I see that my original IPython installation created 
a shortcut with target
C:\Python23\python.exe "C:\Program 
I think you are saying that changing this to
C:\Python24\python.exe "C:\Program Files\IPython\IPython_shell.py"
should work as long as I add an %PYTHONPATH environment 
variable that points to "C:\Program Files\IPython".

Is that about right?

Thank you,

PS And yes, I remembered to add current ctypes and readline 
under 2.4.
