Just a couple suggestions:
In the Security tab, the feature "automatically login as a particular user" does not allow for blank passwords. On my PC I do not protect my login with a password, and I have a Guest account. By default, Vista boots to the login screen, and I would like to be able to login automatically.
Spelling Error on the Advanced tab of SmartGuard. It says "Temperature (Celcius)". Should be "Celsius".
Just my $0.02
