Go get a free copy of Keytweak from here: http://webpages.charter.net/krumsick/
The manual (pdf) is there also. Keytweak lets you turn off keys and reassign keys.
For example, on my keyboard I have the Caps Lock button turned off cause I keep hitting it by mistake. On my elderly notebook, I reassigned the right Alt key to be the Windows key as the notebook didn’t have one.
Cool! I’ll check it out tomorrow at work.
