Just to clarify, did you make any changes to your machine before encountering this issue (like installing third party apps, recent updates, etc..)?

- Select the option to Delete the driver software for this device check box > Uninstall.
- Perform a clean boot: https://support.microsoft.com/help/929135/how-t...
- Double-check if your machine is up-to-date with the latest security patches: Go to Start > Settings > Windows Update > Check for Updates.
- Go back to the Device Manager > Click on the Action tab > select "Scan for hardware changes", and check if it will scan and reinstall your touchpad driver.
Another option is to install the generic driver for the touchpad:
- Open the Device Manager
- Right-click on your touchpad driver and select the Update driver software
- Select the option Browse my computer for driver software > Let me pick from a list of device drivers on my computer.
- Select "HID Compliant Mouse" and follow the instructions to install it.
- Perform a reboot and check again.
