@alone1i, Don't click Restart Now after the drivers installation. In order to use the internal display with an eGPU, you'd need the iGPU to be active and functional. Having an eGPU connected at boot would deactivate the iGPU by default. Therefore you can try booting the computer into Windows without the eGPU then hot-plug the eGPU when Windows finishes loading. If that doesn't work, you'd need to use an EFI boot loader such as the modified apple_set_os v0.5. This is what I'm using to always keep the iGPU activated when booting up with the eGPU connected.
