Nvidia optimus not working properly

I have a issue with nvidia optimus on Windows 10 TP. I installed the latest drivers, but nvidia optimus is still not working.

Anyone knows some workaround to start manually optimus service?

My Laptop is: Lenovo Z510
CPU: i7-4702MQ

RAM: 8.00 GB

nvidia driver: 344


Update: October 3rd

I tried to downgrade Intel Graphics driver to version from the answer. And it still cannot launch some DirectX 9.

The strange thing is that even before the downgrade games that are using DirectX 10 and higher were running without any problems. Only some games that are on Unreal Engine and using DirectX 9, like Mass Effect or Borderlands were not running on Nvidia GPU. And yes, i had already installed DirectX 9.

I'm still gonna leave that reply as an answer, because on nvidia forum  were other people who reported that this workaround fixed their problems.
