Show answer & explanationAnswer & explanation
Correct answer: A. To prompt users for elevated privileges before making system-level changes.
User Account Control (UAC) is a security feature in Windows that helps prevent unauthorized changes to the operating system. It prompts users for permission or an administrator password before allowing applications to make changes that require elevated privileges.
Why the other options are wrong
- B. This describes the function of a firewall, not UAC.
- C. This describes functions of encryption software or antivirus/anti-malware, not UAC.
- D. While digital signatures are important, UAC's primary role is not to verify them, but to manage privilege elevation.
User Account Control (UAC)
A security feature in Windows operating systems that helps prevent unauthorized changes to the computer by prompting users for administrative approval before allowing actions that require elevated privileges.

Memory trick: UAC: User Asks Control.
