The windows distribution (I'm currently looking at 
2.5b3) does not contain a Demo directory, and the 
Tools directory contains only five subdirectories 
(i18n, pynche, Scripts, versioncheck, webchecker)

SVN Head lists 20 directories under Demo and 17 under 
Tools.

At a first pass, all except tools/audiopy (Solaris 
specific) are relevant on Windows, and some tools 
(such as freeze, msi) even have windows-specific code.

I've marked it 2.5 because consistency with other 
platforms seems like a bugfix, even if it does 
introduce new features to windows.  (And note that it 
only adds new files that are not on the standard path, 
which should limit the risks.)
