Screen view has rotated 90 degrees anticlockwise?

Hold down control and alt then press the up arrow

It would help of course if you said which version of Windows etc you are using
'graphics options' are not available on a rt click with Windows 7 each version has a different approach.
If you are using Windows 7 this will work: Rt click the desktop and click on Screen Resolution> change the Orientation from Landscape to Portrait> click apply>click OK.
OK?

Right click on the desktop (background) and hover over Graphics Options - Click on rotation - pick your selection

Make your wife do it.

Try this:
Some computers can rotate the Windows display by 90° or 180°. It can be disconcerting when activated by a mistaken key press. In most cases, holding down Control and Alt before tapping one of the cursor (arrow) keys will fix the problem – the up and down arrows flip the display vertically, the left and right arrows flip it horizontally.
If that fails, in Windows 7, press the Windows key and R, type desk.cpl and press Enter. Press Alt and O, then use the up and down arrow keys to select Landscape. Press Alt and A to apply, then click Keep Changes.
