I believe it's just a symptom of a more pervasive problem:  if you look at
Control Panel in your 2.7b3 Windows installation, you'll see that it
identifies the Zope version as 2.7b2.  Something went wrong with the Windows
installer build process, packaging an odd mix of new and old code.  I'm sure
this will be fixed in the next Zope 2.7 Windows beta.
