My touchscreen capability disappeared

Windows 10 just did an update and ever since I haven't had my touchscreen capabilities. I've checked out various forums and nothing works. I'm about ready to uninstall win 10 and go back to win 8.1,

Dell computer xps 8700, dell monitor T2714.

I couldn't see any way to uninstall the update and can't find they key to enable the touch screen. All my drivers are up-to-date.Any help

Any sugestions? All are appreciated

Still a driver issue if it isn't working.

Check device manager, post screenshot of that with any unknowns.
