I recently purchased a new computer with Windows 10 and the SX2210T Touch screen monitor from my old computer would no longer work. After Dell and Windows updates were complete I went to the device manager and found the HID touchscreen device with the NextWindow 1950 UCS Compliant Touch Screen driver and viewed its properties and then went to the driver tab and clicked 'roll back driver'. The SX2210T touchscreen started working right away.
Thanks for finding a workaround.
So by default on your Inspiron, Windows 10 installed the NextWindow 1950 UCS Compliant Touch Screen driver which did not work. You chose "rollback" which installed what specific driver?
Did you get a chance to test this eGalaxTouch Windows 10 Touch Screen driver?
