Norton (Symantec) Vista UAC Replacement tool

[Sharky]

From their FAQ:

The Norton UAC tool allows an application to run with silently-elevated privileges only in a specific context, one previously approved by the user with the "don't ask again" check box selected.
This means that there is a difference between regedit.exe launched from the start->run box, regedit.exe originating from a shortcut double-click, and regedit.exe launched from a double click on a .reg file (and the context actually changes with each .reg file), and regedit.exe launched by an application (malicious or not).
Given the contextual awareness of Norton UAC tool's automatic responses, the Norton UAC tool provides a usability improvement over Vista's default UAC prompts, while maintaining obvious security improvements in the Vista kernel (such as isolation, file/registry virtualization, and user interface privilege isolation) that are all disabled when UAC is disabled.

Check it out. There is also a checkbox in the installation process allowing you to disable the information they collect (for privacy purposes), however, it's a free product designed not only to reduce how annoying UAC prompts can be whilst still keeping your PC secure, but also to gain this data.
