Turn Off or Disable User Account Control (UAC) in Windows Vista

User Account Control (UAC) is a new security feature in Windows Vista that requires all users to log on and run in standard user privileges mode instead of as administrator with full administrative rights, thus prevent unauthorized or accidental changes that could destabilize the computers or allows virus and malware to exploit the system-level privileges provided to the local administrator to attack the network security, compromise computer safety and privacy, and damage files and settings in the network. However, in a lot of cases, administrator rights are needed by end-users to perform certain tasks such as install or update programs and perform typical system-level task. Beside, many software applications also need administrator privileges to run properly without conflicts, as they are designed to write to system locations during normal operation, and computer in locked-down state in which users operate in standard user mode severely limits user productivity.

In Windows Vista, as and when standard end-user requires administrator privileges to perform certain tasks such as attempting to install an application or write to registry, Windows Vista will prompt a UAC credential prompt to notify the user that a credential of administrator user account is needed for authorization or permission, thus reduce the chance user can accidentally make modifications to vista system files or settings and eliminate the ability for virus or malware to invoke administrator privileges without a user’s knowledge. Even for domain or local administrator, with UAC turns on and enable, most applications, components and processes will run with a limited privilege, but have “elevation potential” or Administrator Approval Mode where administrators must give consent through a User Account Control consent prompt.
