I updated to windows 10 and the Touch display isn't working

I was having the same problem. Many reboots, reinstalls and still nothing. I checked the Touch display settings and they were set correctly to 100%. Here is what I did to fix:

1. Change the Touch scaling from 100% to another number and reboot. (I changed to 125%)
2. After the reboot change the Touch scaling back to 100% and reboot.
3. Launch the MPC software to see if the Touch display works.

Worked for me. Hope this helps someone. Will also post on the akai community page.
