Windows vista and windows 7 offer a security feature which limits privileges of software applications and access to administrative tasks. when a program makes a change that requires administrator-level permission or a user attempts to modify system settings that require administrative access, it triggers an on-screen prompt requiring an administrator password to proceed. this functionality is called:
a. user account control (uac)
b. trusted platform module (tpm)
c. windows firewall
d. windows defender real-time protection
