Keyboard button to disable touchpad stopped working after Windows 10

Forgive me if this is in the wrong area.
I have a Toshiba Satellite laptop. It kept prompting me to upgrade to Windows 10, so I did so.
Now the button that disables my touchpad (also the F5 button) is not working.
The touchpad will not turn off.

Secondly, when I try to move the cursor, the "right click" menu pops up wherever the cursor lands, and it will not let me type. I have to use an external mouse to click out of the menu, then put the cursor back where I wanted it to land.

How can I make the disable button on my keyboard work again, and how can I fix the mouse so that the right click menu only comes up if I actually right click?

Thank you!

No one?

I also have a Toshiba Satellite and am having the same problem, among a couple other issues. I will post here when I find a solution to the touchpad problem.

BTW, I am noticing the touchpad now works like the screen of a tablet. It doesn't work the same anymore. Have you noticed this? I can zoom, etc. This may be a new feature and why the on/off button doesn't work.

After the upgrade is complete, you should be getting the Elan/synaptics update for W10, check you updates.
