Sounds like you have more annoying issues than worrying about security... I think that as long as you do not enable Remote->utorrent remote access, you can feel safe.
BTW, you can disable PUA in your Windows 10. Plus, always make a backup of all your settings files (*.dat) just in case you marked by mistake to delete them while uninstalling....
BTW, you can get the latest (smaller) Beta and just locate if anywhere you like *with* your old setings.dat and other *,dat, no need to install and uninstall.
