User Account Control (UAC) is an important security feature in Windows that prompts users for confirmation when tasks require administrator privileges. This limits the risk of malware making changes without permission. UAC triggers prompts for tasks like running as an administrator, installing active controls, or changing account types. It uses features like secure desktop mode, credential prompts, and elevation prompts to enhance security. Secure desktop mode isolates privileged tasks visually on the desktop. UAC improves security by limiting standard user accounts and requiring explicit consent before tasks can make system-wide changes.
