First check Update and recovery to see If there are updates available. Sometimes, when uninstalled drivers. And restarting the computer they install automatically. It could be there are no drivers for screen touch as they are part of the Windows image. So maybe restoring system to factory settings would solve.

Another thing I found in internet: 'It's possible that your driver is just fine, but another setting in Device Manager could be blocking your touchscreen. Hp Connection Manager Software Windows 7 more. Back in Device Manager's Human Interface Device section, right-click USB Input Device. (If you find more than one of these, try each one.)

Your computer will use more power, shortening battery life.' Try first inserting a pendrive or a mouse to a usb to see if this could enable the touchscreen. Just for prosperity's sake. As of November 15th 2015: The key to the touchscreen is the 'Intel Serial IO' driver. On a fresh install of Windows 8.1 HP Support will not pick this up as a necessary driver, you have to find it on the support site and it lives under 'Display/Video Drivers'.

On a fresh install of Windows 10 you will lose the touchscreen because there is no Windows 10 version of the 'Intel Serial IO' driver and the 8.1 version from Intel won't install on 10. In theory, you can upgrade to 10 because Windows 10 will 'grandfather' in the 8.1 drivers. However, I've noticed on some machines this causes instability in the long run. Don't know about the stream though, I am waiting till Intel releases the 'Serial IO' driver for Windows 10 to upgrade. Just an FYI in case anyone needs it.
