That should work, but means you're stuffed if you want ot go back to 
2.7.1 for any reason...

Well, what I've done, and has worked for years on both Linux and 
Windows, is to install the Zope software in folders related to their 
version, eg:

E:\Zope\2.7.1
E:\Zope\2.7.4

I think create projects as instance homes:

E:\Zope\myproject1
E:\Zope\myproject2

Then, all I need to do to upgrade is install the new zope software 
(putting 2.7.whatever in the location box for the binary installer) and 
then tweak the start scripts (you'll have to fiddle with the service 
start scripts) and zope.conf's of the instances I want to upgrade, 
restart them, and you're done :-)

cheers,

Chris
