Why can't I see the tabs on my Windows Task Manager?

I have no clue what I did, but whenever I go to look at my Windows Task Manager, I can no longer see the tabs labled "Processes", etc.. at the top. What did I do, and furthermore, and can I do to get them back? Thanks for your help.

Here's an example of what I'm seeing in case you're interested.

in the space above the area that says task, double click it. should come back

Thanks very much for dealing with such a moronic / simple question. Much appreciated!
