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'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:

It's not easy, which is why we haven't got around to doing it so far.
