Version Helper functions
The following functions can be used to determine the current operating system version or identify whether it is a Windows or Windows Server release. These functions provide simple tests that use the VerifyVersionInfo function and the recommended greater than or equal to comparisons that are proven as a robust means to determine the operating system version.

| IsWindowsServer |

| IsWindowsVersionOrGreater |
Note You should only use this function if the other provided version helper functions do not fit your scenario.
Indicates if the current OS version matches, or is greater than, the provided version information. This function is useful in confirming a version of Windows Server that doesn't share a version number with a client release. |
Example
The inline functions defined in the VersionHelpers.h header file let you verify the operating system version by returning a Boolean value when testing for a version of Windows.
For example, if your application requires Windows 8 or later, use the following test.
#include <VersionHelpers.h>
…
if (!IsWindows8OrGreater())
{
MessageBox(NULL, "You need at least Windows 8", "Version Not Supported", MB_OK);
}
