No, this is different, but supplied with manifest resource/file too. I tested
it again just now and it's probably easier than I thought - it doesn't register
everything on load but on first class use with CreateWindow(). That means
user32 has to check for current (or not only current?) context data and then
override registration with RegisterClassNameW, another thing is that it
probably alters context to mark class are re-registered, cause this function is
called only once.
