Both responses indicate the same approach, going to Touchpad Settings and then selecting Additional Settings. But when I do that, I don't get the screen that the tutorials indicate, I have no option to disable tap to click or the settings around gestures. When I click Additional Settings I just get the Mouse Properties dialogue box, which doesn't have any options for modifying the Touchpad settings. Clickpad Settings is not a tab or button in my dialogue box. I do have a Hardware Tab, which shows the Synaptics Touchpad as the installed device, but when I highlight that and click Properties, then Change Settings, it takes me to a dialogue window like the Mouse Properties dialogue that has no options for changing the settings.
I'd love to give you a screen shot, but the print screen function no longer works on my laptop after a recent Windows 10 upgrade.
