Hey Nils,
Keep in mind that Express edition of VS2010 should work as well, and you can install them side-by-side. In regards to updating the prebuilds, I am hoping to be able to do this for our next release on March 3rd, though this may slip as we may need to refactor the code that handles our binding to support prebuilt for both Node 0.10 as well as Node 0.12.
Cheers, Brett
