Enter "vertical bar" (or "pipe symbol") in Windows

I have my MacBook late 2008 sometimes running Windows 7 via BootCamp. The keyboard has a German layout. Pretty much like the Wikimedia image below except that the blue symbols in the lowest line are not accessible.

How could I enter the vertical bar | via my keyboard?

Unfortunately Right Alt + < does not seem to work. (However, I can enter @ with Right Alt + Q et al. as I can do on external keyboards.)

Update2: From what I can tell from the languages settings, the Windows layout is missing the <-key between Left Shift and Y. What layout would provide it?

Update 3: On a co-workers current MacBook Pro its working as expected.

I'd also be happy with some comments suggesting ways to have it entered. I'm tiered of copying it from Wikipedia every time.

My US English Qwerty keyboard has it as Shift-\, with the \ key right above the Return key.

I had the same problem with the German keyboard. Press the key <>| and Alt and Strg key together. It works!

You see, there is already the vertical line sign on the double arrow key if you notice clearly.

Try

cmd + Shift + <

Re-reading your question, I looked at some standard German Keyboard layouts and you have the <>| key in the bottom left hand corner of the layout.

The only issue you have is the right hand Alt (cmd) doesn't do anything different than the left one!

See the image to show where the keyboard is defined in Windows 7: Edit: added screenshot of which keyboard layout (in English unfortuantely)

I think everyone's experience varies..on a us-keyboard on en-gb system:

right alt-key + '~' worked
