Shcore. Dll on Windows 7 -- Does It Exist?

I am trying to use this function, but I don't have shcore.dll and I can't figure out where to get it. Is shcore.dll just a Windows 10 DLL?

   [DllImport("Shcore.dll")]
        internal static extern IntPtr GetDpiForMonitor(
            [In] IntPtr hmonitor,
            [In] MonitorDpiType dpiType,
            [Out] out uint dpiX,
            [Out] out uint dpiY);
