There is only one sensible suggestion now and that is to re-install Windows 10 and let Windows Updates get on with updating your Graphics system on your Laptop.
It should automatically install the Intel HD and Nvidia drivers in the correct order.

That has worked on my Intel HD graphics and GT740M Optimus Laptop for over 3 years during Windows 8.1 and Windows 10.

The video you reference is out of date and you are unlikely to get an Nvidia Control Panel like that, it's not on mine, fewer options.

Ignore suggestions from Desktop graphics card users they don't realise the more limited options of Nvidia Optimus systems.
