Question

Working on a project and need to be able to determine whether the O/S is Windows 7, Vista or default to XP. I understand I could run into Win2K and earlier versions but let’s just say that’s not a concern as other code will catch that before it gets to this point. My application will be in C++ for the time being using VS2005. I’ve found articles and sample code alike but they seem way bloated for my uses. Just looking for a quick and dirty return.
