Question

which common occurrences require a higher level of user account control? choose two answers. visits to unfamiliar websites being the only user on a pc installations of new apps and software visits to familiar websites changes to display settings

Explanation:

User Account Control (UAC) prompts for elevated permissions when there are significant system - level changes. Installing new apps/software can modify system files and settings, so it requires higher UAC. Changes to display settings can also impact system - wide configurations (e.g., if it involves driver updates or system - level visual changes), thus needing higher UAC. Visiting websites (familiar or unfamiliar) typically doesn't make deep - seated system changes that require UAC elevation. Being the only user on a PC doesn't inherently trigger UAC for its own sake.

Answer:

Installations of new apps and software, Changes to display settings
