Mount a ext3 partition?

i would like to mount a ext3 partition on windows but I don't know how to do it. Can anyone tell me how i would do this? My OS is windows vista.

create mount point for new partition, open /etc/fstab file
Code:

sudo mkdir /media/new_p
sudo gedit /etc/fstab

and add this line in /etc/fstab file
Code:

/dev/<new_partition> /media/new_p ext3 defaults,umask=0 0 0

press 'Enter' key at the end of this line. Last line should be blank in 'fstab' file.
