I don't think there is an easy way on Windows, but I could be wrong. You 
could try asking on a dedicated iPython mailing list. If you get an 
answer, please come back and tell us here so we can learn too.

On Linux, install the ipython3 package. On Debian or Ubuntu systems, 
try:

sudo aptitude install ipython3

and then run ipython3 instead of ipython. On Centos or Fedora systems:

sudo yum install ipython3

will probably work if your system isn't too old.

Or, you could try the instructions shown here:

http://stackoverflow.com/questions/9386048/ipython-reads-wrong-python-version

but I would be surprised if it works.

(I just tried it, and it failed. You need to install all the ipython 
libraries into Python 3.)
