Rotate Screen in Windows

Walked into the office the other day and the receptionists screen image was rotated by 90 degrees – see below!

We desparately tried to work out how to resolve it whilst twisting our heads and getting a sore neck in the process.

To avoid getting a sore neck use the following key strokes to resolve:

Press the Ctrl and Alt keys together and then press one of the arrow keys:

Ctrl Alt up arrow (normal screen)
Ctrl Alt right arrow (rotate 270°)
Ctrl Alt left arrow (rotate 90°)
Ctrl Alt down arrow (rotate 180°)

A full list of Microsoft keystrokes can be found here: http://support.microsoft.com/kb/301583, but the ones above are not listed for some reason.

Can only assume that the cleaners accidently hit one of the keystrokes overnight.
