Touchpad not working Dell E6410 - win10 Pro update

I´m running Win10 Pro and everything was fine until the latest Windows update.
The touchpad stopped working abruptly.
I´ve tried to uninstall and reinstall the latest driver and nothing.
Going to definitions mouse/touchpad, in mouse everything's ok but for the touchpad I just have the sensitivity option, no on/off mode, nothing.
Got to device manager >> mouse and pointing devices>> Dell touchpad>> tried to uninstall/reinstall driver and everything seems ok, but it still does't work.
Don't know what else to do, I'm thinking to reverse it back to factory settings and to Win7.

I think it's the 1709 (automatic update), but I'll confirm it later today. And will disable all automatic updates in the future.

it is the 1709 (OS compilation 16299.64)

First of all thanks to Dalchina for his advices.

It was just a driver "bug" I installed the Alps 10.1207.101.109 version and the touchpad is working perfectly now.
This site here http://dellwindowsreinstallationguide.com/dell-touchpad-drivers/#Latitude has very usefull info but just for Dell owners I'm afraid.

I have five Dell Lattitude E6410's here all with a sticky touchpad. Sometimes works, sometimes sticks for a few seconds. Been going on for some time now, so its not a recent update type problem.

Just done a big update to version 1803 and the problem remains, so tried running the Alps 10.1207.101.109 file from the site you quote, but it refuses to install. I just double clicked the exe file. The driver install said successful, but when I closed that, a Dell box then came up saying it was unsuccessful. Have I missed a trick here?

You might try installing in compatibility mode; Defender Controlled Folder access may be playing a role here (various problems reported with Defender in 1803).

Also try installing as admin (rt click run as admin).

Just ideas - feel free to post the exact error messages.
And what driver version is now shown in Device Manager?

Tried all that, with the same result. The compatibility mode was for Windows 8, and I r clicked and ran as administrator as you suggested. Device manager shows 8.1206.101.112
