Detecting SSD in Windows

I would like to change the performance and behaviour of my C++ application, according to whether the system drive is an SSD or not. Example:

• With SSD, I want my gameserver application to load each map fully, with all objects in order to maximize performance.
• With HDD, I want my gameserver application to load only the essential objects and entities in each map, with no external objects loaded.

I've seen http://msdn.microsoft.com/en-gb/library/windows/desktop/aa364939(v=vs.85).aspx, which is a way of determining if a certain drive is a HDD, CD ROM, DVD ROM, Removable Media, etc, but it STILL can't detect whether the main system drive is an SSD. I've also seen Is there any way of detecting if a drive is a SSD?, but the solution only applies to Linux.

I thought that I could somehow generate a large fine (500MB), and then time how long it takes to write the file, but however other system variables can easily influence the result.

In Windows, using C++, is there any way to get whether the main system drive is an SSD or not?

You can use the Microsoft WMI Class MSFT_PhysicalDisk. The mediatype of 4 is SSD and SpindleSpeed will be 0.
