I often run full-screen RDP sessions from one Windows 8.1 system to another. Since the task bar is placed in the same location (the bottom of the screen) in both, and the task bar by default is slightly translucent, this leads to task bar buttons from one system to show through as a sort of task bar "background" on the other.
How do I configure the Windows 8.1 task bar to be fully opaque, avoiding this issue?
