I think what you want is explained here on MSDN. Basically, you #define WINVER to indicate the target operating system.

This is the relevant part of that page:

Setting WINVER or _WIN32_WINNT

You can define these symbols by using the #define statement in each source file, or by specifying the /D compiler option supported by Visual C++.

For example, to set WINVER in your source file, use the following statement:

#define WINVER 0x0502

To set _WIN32_WINNT in your source file, use the following statement:

#define _WIN32_WINNT 0x0502

To set _WIN32_WINNT using the /D compiler option, use the following command:

cl -c /D_WIN32_WINNT=0x0502 source.cpp

For information on using the /D compiler option, see /D (preprocessor definitions).
