Which of the following is NOT a function of the User account control (UAC) monitoring policy?

The monitoring policy of User Account Control (UAC) is primarily geared towards ensuring that administrative tasks are performed only with the appropriate permissions and that users are aware when elevated privileges are being invoked. This involves functions such as tracking administrative privilege usage, auditing user access levels, and generating reports on user activity to maintain oversight and improve security postures.

Blocking unauthorized access, while a critical aspect of security, is not a specific function of UAC monitoring policy. Instead, UAC serves as a mechanism to inform users about potential privilege escalations and requires their consent before allowing certain actions, but it does not inherently block access on its own. Instead, it places controls in the hands of the user to prevent unauthorized changes by prompting for elevation when needed. Thus, this option does not align with the primary focus of UAC monitoring policies.
