free virtualbox vm of windows 8

Question

As a web developer I've used the free vm's microsoft provide for testing (doctored and configured for easy installation on Linux and OSX with virtualbox).

Does anyone know if there's an equivalent for Win8? (something that's been OK'd by Microsoft - not just a rip-off copy).

Answer 1

The closest thing I can think of off hand is the windows 8 enterprise evaluation (which will run for 90 days before needing an install). Technet had the same for windows 7 I believe at one point.
