I could find stdio.h header file easily through search in Windows Explorer, but couldn't find its implementation file like stdio.lib(?). Where can I find it?

Additionally, I can't find Windows.h through search in Windows Explorer, although I can compile source code with Windows.h included.

Is there anybody to explain about this?

The sources for the CRT (C Runtime) are included in the Visual Studio install directory, under VC\crt\src. There are many files; you'll need to find the one that defines the functionality in which you are interested.

The Windows headers (including Windows.h) are included in the Windows SDK, in which there is an Include directory which contains the headers. Where exactly these files are located on your computer depends entirely on where you installed the Windows SDK.
