DtWinVer

DtWinVer: Comprehensive operating system detection class to get various information on the OS

DtWinVer is a powerful C++ class that lets you see which OS the program that calls it is running on. What's probably even more interesting is that DtWinVer is capable of handling both emulated and underlying operating systems.

The software class comes packed into a zip archive with the source code along with some project files that can help you create a test run for most Windows operating systems as well as DOS. There are many possible scenarios in which you can use DtWinVer and while there's a bit of a learning curve, in the end, it's relatively easy to implement and use.

If you want a powerful class for providing you details on OS applications calls, DtWinVer is the best tool for the task.
