The main thing is to be able to run Microsoft's sysprep tool on a Windows guest. Chris wrote some code to do this already in this branch of oz, but it's very complex: https://github.com/clalancette/oz/tree/win2k8customize See in particular: https://github.com/clalancette/oz/blob/win2k8customize/oz/Windows.py People will also want to set the hostname (--hostname option) and run scripts (--script option).

Windows has a sysprep tool which does the right thing for all Windows guests, and it's impossible to know what that tool does or replicate

it. However it requires a multi-step process to run sysprep on a guest, so we should make that easier for users if we can.

Definitely not. In modern versions of Windows, it is included (under %systemroot%/System32/sysprep). For older versions you had to download it as a separate tool. >> it.

It's pretty complicated. Probably the best thing is to read Microsoft's documentation on how to use it: https://encrypted.google.com/search?q=sysprep+site:microsoft.com in conjunction with the Oz code: https://github.com/clalancette/oz/blob/win2k8customize/oz/Windows.py It's not easy, which is why we haven't got around to doing it so far.
