GetVersionEx under Windows 8
According to several comments in the MSDN forums and this article the version number for Windows 8 is 6.2
This is the sample code updated and tested in Windows 8 Developer Preview

OK, I was hoping someone has done this already ... but, I guess not, so here you go:
Windows 8 Consumer Preview
//OSVERSIONINFO for GetVersionEx returns:dwMajorVersion = 6;dwMinorVersion = 2;wProductType = 1;//GetProductInfo returns:dwType = 0x4A; //Not documented yet???PS. I don't have VS IDE installed there. Had to make a small app to get those...
