Windows Platforms (CRT)

The C run-time libraries for Visual Studio support current versions of Windows and Windows Server, [!INCLUDEwin8], [!INCLUDEwinserver8], Windows 7, [!INCLUDEwinsvr08], and Windows Vista, and optionally support [!INCLUDEwinxp] Service Pack 3 (SP3) for x86, [!INCLUDEwinxp] Service Pack 2 (SP2) for x64, and [!INCLUDEWinXPSvr] Service Pack 2 (SP2) for both x86 and x64. All of these operating systems support the Windows desktop API (Win32) and provide Unicode support. In addition, any Win32 application can use a multibyte character set (MBCS).

Note

The default installation of the Desktop development with C++ workload in Visual Studio 2017 does not include support for [!INCLUDEwinxp] and [!INCLUDEWinXPSvr] development. You must install the optional component Windows XP support for C++ to enable a Windows XP platform toolset.
