The 1st parameter of CreateWindowW() takes an LPWSTR (wchar_t*) pointer, but RegisterClassExW() returns an ATOM (unsigned short) handle instead.

lpClassName

Type: LPCTSTR

A null-terminated string or 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. If lpClassName is a string, it specifies the window class name. The class name can be any name registered with RegisterClass or RegisterClassEx, provided that the module that registers the class is also the module that creates the window. The class name can also be any of the predefined system class names. For a list of system class names, see the Remarks section.

So you would need a type-cast. Use the MAKEINTATOM() macro for that:

Converts the specified atom into a string, so it can be passed to functions which accept either atoms or strings.
