When I installed Windows 10 I could left click on the volume control and a slider appeared where I could adjust the volume. Now when I left click nothing happens. To adjust volume I have to right click open Volume Mixer to adjust volume. How can I restore this back to left clicking to adjust volume. At the same time this feature went away left clicking on the Windows Icon in the tray also stopped working. Now to shut down or sign out I have to right click to get to do this. Anyone else had this problem
