I think you should uninstall Diskeeper and TuneUp utilities and not use them at all. You don't need them. I don't think you need HDDLife Pro either. Windows 7 just does not need all that stuff. And while I am not a fan of Norton, I accept it is a good security program - however, it is known to be a big resource hog with many features you just don't need. If Norton stops serving you well, consider one of the several free alternatives, such as MSE.
Also, if I may ask, why are you upgrading to Ultimate? Understand you will see zero performance gain with Ultimate. As seen
here, all you get with Ultimate over Pro is BitLocker support (which most users don't need) and multiple language support, which again, must users don't need. It is not a "better" Windows 7. It just has a few additional features, costs more, and consumes more disk space.
