Two of my 3 computers have the Windows 10 reservation app in the lower right notification area. One has Windows 7, the other Windows 8.1. My newest laptop (Yoga Pro 3) has Windows 8.1 with all the latest updates but does not display the reservation app. I do not have any of the issues mentioned on the Microsoft help page on why it may not appear. My Windows is genuine and activated. How should I proceed?
