WINDOWS 7…………………………..?

These have suddenly disappeared with the little bar at the bottom.
I went to ‘Customize’ > ‘Turn Process Icons On/Off’, but while i try in order to click ‘On’ for that volume, it’s greyed away, I can not click that.

What must do

Go into customize and mouse click on Restore Default Icon Behaviour.You can receive there simply by right clicking the Undertaking Bar in addition to choosing Qualities.
