Scenario: I open 3 Visual studio 2015 instances in particular order so that when switching between them via task bar hover preview I know exactly which project is at first position and so on. I can simply move my mouse on the grouped Visual studio icon in taskbar and without paying attention click on one of the 3 hover previews of the instance I want to open.
Problem: But, due to some unknown reasons Window 10 sometimes reorders these previews (inside the group) and I often click on the wrong VS instance expecting it to be another. Furthermore, I cannot drag-drop within hover previews to re-order them and the only way to reset the order is to close all instances and open them again one-by-one in the order I want.
What is causing this behavior? How can I at least re-order these hover previews without closing and re-opening all VS2015 instances?
