"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This is a warning, not an error, and is very common when upgrading a Visual C++ project. This is the macro that defines what the lowest version of Windows that our application will run on. If we ignore the warning, we accept the default value, _WIN32_WINNT_MAXVER, which means the current version of Windows. For a table of possible values, see Using the Windows Headers. For example, we can set it to run on any version from Vista onwards.


If the code uses parts of the Windows API that aren't available on the version of Windows that you specify with this macro, you should see that as a compiler error

define it before including windows.h
