Overview: One of the most welcome features in Vista is User Account Control, formerly called User Account Protection (UAP), and before that, Least-privileged User Account (LUA). Running the machine as a high-privileged administrator is a bad idea since it means any download-and-install from the internet (whether deliberate or otherwise) gets installed and runs using admin credentials. If the software is ""Mal-intentioned"" then one could be in a heap of trouble. Running the machine as a standard (low-privileged) user, on the other hand, means that any software one establish and runs can do only a limited amount of damage.
