ELAN UltraNav Driver 10 - Trackpad stopped working

I did a search to see if this was already posted but didn't find it.  So, here's my story.

 

I have a P40 Yoga that's about a year old.  A couple of weeks ago, I received a pop-up from Lenovo Vantage saying there was a system update.  Like a good user, I said OK.  I didn't notice it right away (because I use an external mouse) but the trackpad, left/right click buttons and the "trackpoint" center button all stopped working.  I did a lot of searching to see if there was a resolution but couldn't find one.

 

Eventually, I went into Control Panel | Device Manager | Mice and other pointing devices | ELAN pointing device | Driver and saw that there was a recent update.  Fortunatly, there was a "Roll Back Driver" option which I figured couldn't hurt anything.  After a reboot, the driver is back to one dated 2/13/2017 version 11.21.9.3.  All mouse accoutrements are once again working.

 

What prompted me to post today is that the Lenovo Vantage pop-up appeared again telling me there's an update and it wants to put the bad driver back. Irconically, the pop-up says:

 

"Lenovo recommends that you install these updates to optimize your computer"

 

Yah, right!  Now I'm sceptical about ever doing another update.
