Chapter 3. Operating Systems > UAC and the Administrator Account

UAC and the Administrator Account

The User Account Control (UAC) asks the user for permission when a program requests access or is about to run a task that might harm the PC.

In the NT/2K/XP/Vista environment, administrators can access everything. NT, 2K, and XP have hybrid users (like power users) who have some admin privileges and guests who essentially have none. For security reasons, guest accounts should always be disabled. Vista’s administrator account is disabled by default, relying on the UAC to control access to administrative privileges. To force a program to run in Administrator Mode, right-click the icon and choose Administrator Mode. This requires an administrator password. Some programs only run in this mode, which prevents end users from making catastrophic changes.
