The are used to determine the version of the operating system that is currently running. For more information, see. The following table summarizes the most recent operating system version numbers. Operating system Version number Windows 10 10.0. Windows Server 2016 10.0.

Windows 8.1 6.3. Windows Server 2012 R2 6.3. Windows 8 6.2 Windows Server 2012 6.2 Windows 7 6.1 Windows Server 2008 R2 6.1 Windows Server 2008 6.0 Windows Vista 6.0 Windows Server 2003 R2 5.2 Windows Server 2003 5.2 Windows XP 64-Bit Edition 5.2 Windows XP 5.1 Windows 2000 5.0. For applications that have been manifested for Windows 8.1 or Windows 10. Applications not manifested for Windows 8.1 or Windows 10 will return the Windows 8 OS version value (6.2). To manifest your applications for Windows 8.1 or Windows 10, refer to.

Identifying the current operating system is usually not the best way to determine whether a particular operating system feature is present. This is because the operating system may have had new features added in a redistributable DLL. Rather than using the to determine the operating system platform or version number, test for the presence of the feature itself. To determine the best way to test for a feature, refer to the documentation for the feature of interest. The following list discusses some common techniques for feature detection:. You can test for the presence of the functions associated with a feature.

To test for the presence of a function in a system DLL, call the function to load the DLL. Then call the function to determine whether the function of interest is present in the DLL. Use the pointer returned by GetProcAddress to call the function. Note that even if the function is present, it may be a stub that just returns an error code such as ERRORCALLNOTIMPLEMENTED. You can determine the presence of some features by using the function. For example, you can detect multiple display monitors by calling GetSystemMetrics(SMCMONITORS). There are several versions of the redistributable DLLs that implement shell and common control features.

Windows 2000 Final. Windows 2000 was a modernization of Windows NT 4.0 which brought many of the desktop changes, including Active Desktop, to Microsoft's Windows NT.

For information about determining which versions are present on the system your application is running on, see the topic. If you must require a particular operating system, be sure to use it as a minimum supported version, rather than design the test for the one operating system. This way, your detection code will continue to work on future versions of Windows. Note that a 32-bit application can detect whether it is running under WOW64 by calling the function. It can obtain additional processor information by calling the function.
