Can you not copy the contents of the %appdata%\utorrent folder (from your old Win installation) and then paste into the new %appdata%\utorrent folder? (whilst uTorrent is not running obviously). There are a Settings.dat & Resume.dat file in there I think which should contain your previous uTorrent settings. (You might wanna backup your current ones first (copy the folder to a separate drive/USB stick), just in case as I think it will do a straight replacement rather than migration).

It's always best practice to keep data and software on separate drives (volumes/partitions) then if you do need to reinstall your OS, your data remains untouched.
