Windows No-Install Distribution?

[Eric Lemings]

Hi,

I would like to create/find a Python 3.x distribution that can be
redeployed simply by copying a directory of required files; i.e.
without the need for actually "installing" an MSI, modifying Windows
registry entries, etc.  First of all, will Python even work on Windows
simply by copying files from one system to another?  If so, does such
a "no-install" distribution already exist?  If not, what are the
minimum set of Python 3.x files from a standard Windows Python
installation required for proper/normal operation?

Thanks,
Eric.
