I have been trying to remove multi-window functionality on my Nexus 6 Android with Nougat as I am the only user and I discovered Multi-user functionality breaks my custom Tasker profiles.
I have tried to incorporate solutions using adb by setting guest_user_enabled to 0 as described in solution linked below, but either 1) I need root access, 2) I am not implementing adb correctly, or 3) The solution is outdated and out of my experience level to implement in Nougat.
Any and all help is greatly appreciated as I have hit a wall. I created an account specifically for this problem.
