Which version and edition Windows did you originally upgrade from or was installed prior to your current version:
Windows 10 - 1703, 1607, 1511, 1507 (build 10240)
Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro
Press Windows key + X
Click Device Manager
Expand Human Interface Device
Right click HID Compliant Touchpad
Click Disable
Also look on your keyboard for an option to disable it
Look for a block or lock symbol on any of the function (F1 - F12) keys. Mine is Fn + F7 to disable the touch pad.
In addition the latest touchpad software should include a setting which if chosen will disable the touchpad whenever an external USB pointing device is connected. This is the safest way to handle this so you have touchpad working if mouse dies or you leave it at home.
Once the latest touchpad software is installed from the PC's Support Downloads webpage, look for this setting at Settings > Devices > Touchpad and also in the Additional Settings there at the right side of the page to open Mouse Properties and look at the last tab where the Touchpad software installs itself.
