Supported OS for 2015 Driver Station?

[dcerys]

Which OS versions (of Windows) are likely to be supported for the 2015 Driver Station? I see that one of the Beta teams (Team 868) mentioned that you should use "Windows 7 or 8" for setup, but I'm not sure whether that is a DS requirement (or just a recommendation).

Motivation: our Driver Station laptops have Windows Vista installed, because that's the way they came when they were donated to us. Most of our team's programming is done on personal Macs (in Java). So, the question is: do we want to upgrade our Driver Station laptops to Windows 7 or 8 this fall, or do we need to upgrade?

Thanks,
Dan
