Bingo, put it in DFU mode and it will work. Plug it in to the computer with iTunes open, and hold the power button and slide it to turn it off. Once it is off then hold the home button for 5 seconds, then while still holding the home button and never letting go hold the power button for 10 seconds, then let go off the home button and continue to hold the power button for up to 30 seconds. It should take around 15-20 seconds to install the driver on Windows. iTunes will pop up and report that the iDevice is in Recovery Mode. Click restore or whatever and bingo.
