I upgraded my window 7 to window10 but touchpad is not working .
I checked for drivers reinstalled it but still touchpad not working .
I even used the fn key fn+f4;fn+f9 ... even all f keys but still the touchpad not working .
Then I went to start ; setting ; devices; mouse and touchpad and then additional setting and there are options button pointer pointer option wheel hardware and I cannot see any touchpad option .
I looked for all online support but no touchpad option is visible .
I tried Dell support I downloaded drivers for touchpad and mouse still it's not working .
All the time I have to use external mouse .
I even opened the bios and did full system scan during the scan the touchpad works but as the computer switches on to windows10 the touchpad is not working .
Please help me out its around 7 days I am using my external mouse to do the work .
You can mail me at ***@***.

Try uninstalling it from the Device Manager - restart your computer and let windows to find and install it automatically. It seems to be some incompatibility between your operating system and your device.
