How can I make a screenshot on Macbook pro using Windows 7? The keyboard does not include a special key for this function.
If you are using Bootcamp, Apple has provided documentation of key mappings:
print screen = fn + ⇧ shift + F11
Your best option would be to use the snipping tool that comes with Windows 7.
Like Davo says, use the on screen keyboard when you can not use or remember the key combo.
Start -> Accessories -> Accessibilty -> On screen keyboard. Then slide it mostly out of the way while you can still click the print screen key with your mouse pointer. Edit away the on screen keyboard from the shot later if you want to.
Try using the on screen keyboard and hitting the prt scrn button
