By default, administrators using Windows Vista are running in a new execution mode
called Admin Approval Mode. This is the reason you see consent dialog boxes appear
from time to time. You can actually disable this mode, making administrator accounts
work more like they did in XP, without any annoying dialog boxes popping. However,
you should realize that disabling Admin Approval Mode could open up your system
to attack. If you’re still interested in disabling this feature, or disabling User Account
Control, we will discuss ways to do so at the end of this section.
Conversely, administrators who would like Windows Vista to be even more secure
can also configure the system to prompt with a User Account Control credentials dialog
box—which requires a complete password—every time they attempt an administrative
task.
