Every one of the methods listed for accessing the Start menu in Windows 8 causes problems in a remote desktop connection.

-The mouse isn't always locked into the active rdc window, so finding the corner of the screen is tedious

-Swiping in from the side of the window with a mouse doesn't work

-Pressing the Start key on your keyboard will open the host Start menu, not the remotely connected instance

Of course rdc is a bit of an edge case, but it's very important for business/power users.
