 User32 user-mode library layout tree

User32.dll is a user mode DLL library that provides windowing manager APIs to the client. An example of a call brought by the said library is CreateWindowExW which creates a window with extended styles. The documented function calls in the User32.dll library rely on undocumented internal functions in Win32k, the kernel mode side of the Windows subsystem.
