SOLVED: Laptop Touchpad fully functional, but not in Universal apps

OK - sorted it finally :

• in step one/two above you delete the existing Synaptics drivers then have to reboot
• unfortunately when the PC restarts it installs some generic touchpad drivers which have the basic functionality
• So although step4 (run setup) appears to work, it hasn't actually done anything as the generic drivers are already there

So what you have to do is this...

• In device manager, select the mouse device and click update drivers.
• Then select Browse My Computer > Let me pick from a list > Have disk button, and select the folder with the new Synaptics drivers (I'm running 32-bit windows so selected ..\WinWDF\x86).
• The green progress bar shows the drivers are loading, then when it's all done you now have the new functionality installed - RESULT!!!
