/// <param name="lpClassName">
/// Type: LPCTSTR
/// A null-terminated string or a class atom. If lpClassName is a string, it specifies the window class name.
/// This class name must have been registered by a previous call to the RegisterClass or RegisterClassEx function.
/// System classes, such as dialog box controls, cannot be unregistered. If this parameter is an atom,
/// it must be a class atom created by a previous call to the RegisterClass or RegisterClassEx function.
/// The atom must be in the low-order word of lpClassName; the high-order word must be zero.
/// <param name="hInstance">
/// A handle to the instance of the module that created the class.
/// Type: BOOL
/// If the function succeeds, the return value is nonzero.
/// If the class could not be found or if a window still exists that was created with the class, the return value is zero.
/// To get extended error information, call GetLastError.
