In general, you should be able to run Zope 2.6.2 with Python 2.2.3
without issues (but *don't* use Python 2.2 - 2.2.2, nor Zope 2.6 - 2.6.1
in this mode!).  I'm afraid I don't know enough Windows majyk to tell
you an easy way to upgrade the Python on the box;  I would install 2.2.3
separately, and then hack the startup.bat (or whatever) to use that
Python.

We are looking to release Zope 2.7b3 (which will prefer Python 2.3),
soon,  Here is what Brian wrote yesterday:

There are substantial performance benefits (at least on the platforms I
know) in moving from 2.1.3 to 2.2.3.  I am told, and believe, that 2.3.2
will provide further such benefits.
