When I first set up Windows 8 (core edition) on my desktop PC, it showed the following behavior when I right-clicked a start screen tile:
It was possible to right-click multiple tiles and use the ribbon to act on all of them.
After a few hours, without my reconfiguring anything obviously related to the start screen, it changed so that right-clicking brings up a context menu instead:
Now if I want to act on multiple tiles, I have to ctrl-click them and then right-click to select an action.
What caused this change? How can I get the ribbon back?
