It is a good idea to back up the library files, iTunes Library.itl and iTunes Music library.xml before upgrading. It shouldn't be necessary but your never know... You may be glad of it if you want to downgrade.
If you want easy downgrading, save the last iTunes set up file if you have it, maybe rename it iTunesseteup8.exe so it isn't overwritten by the new installer.
It is safest not to upgrade from in iTunes.
Download the installer from the Apple site and save it on your PC, then run it from you PC.
The installer takes care of any uninstalling that is needed.
