Look at that screenshot that you posted. That is a MacBook Pro laptop computer that is showing. Look at the very top of the screen in the screenshot next to the Apple logo you will see iTunes. Next to the word iTunes, you see File.
You are running Windows and I am Winodws illiterate, but try clicking on that square icon in the upper left corner of the window - the square above the word "Music".
Maybe this will help.

One of the most knowledgable iTunes for Windows users in our community, turingtest2, has a number of helpful user tips and when iTunes 11 came out, he posted this and it might be helpful as well.
In Windows, you can restore much of the look & feel of iTunes 10.7 with these shortcuts:
ALT to temporarily display the menu bar
CTRL+B to show or hide the menu bar
CTRL+S to show or hide the sidebar
CTRL+/ to show or hide the status bar (won't hide for me on Win XP)
Click the magnifying glass top right and untick Search Entire Library to restore the old search behaviour
Use View > Hide <Media Kind> in the cloud or Edit (iTunes) > Preferences > Store and untick Show iTunes in the cloud purchases to hide the cloud items. The second method eliminates the cloud status column (and may let iTunes start up more quickly)
If you don't like having different coloured background & text in the Album (Grid) view use Edit (iTunes) > Preferences > General and untick Use custom colours for open albums, movies, etc.
With iTunes 11.0.3 you can enable artwork in the Songs and playlist views from View > Show View Options (CTRL+J) making it more like the old Album List view.
