Haven´t tried what Lev said, using the new ISO, but as the person who
wrote the wiki page, yes, you need to install _either_ python or, as Lev
said, the VC runtime for the exe's to work on each guest.

In practice though you create a template with this installed _one_ time,
then spawn the rest of your VM's from that. But e.g. converting lots of
VM's that came from another virtualization platform you´d need the VC
runtime (or python) and exe's installed in each VM for the guest agent
to work.

Do you know there´s a third-party package manager for windows called
"Chocolatey", kind of like yum for Windows? That together with Puppet
(or plain-old SCCM) makes Windows management lots easier.
