When trying to establish remote sessions from iPad to Windows 10 computers with Windows 10 Anniversary update installed (KB3176929), the touch function will not work during the remote session.
Go to Device Manager on the Windows 10 computer, find Splashtop Virtual Hid under Human Interface Devices, right click to disable it. Then the touch function will work again.
- Trackpad mode still works with Hid driver installed.
- You could check if you have Windows 10 Anniversary update installed under Programs and Features / View installed updates.
