I honestly do not remember if I installed them in that order. I just followed the prompt when it asked me if I wanted to install windows 10.
Also, I tried downloading the driver from the Dell Website but was unable to. There was no driver for the touchpad. I used the link from that video to get the driver.
Can you uninstall the touchpad driver and let Windows install touchpad driver don't install any touchpad driver if its not from laptop manufacturer website.
