The default setting for User Account Control (UAC) improves Windows Security primarily by notifying users of software installation attempts. When software is installed on a computer, it often requires elevated permissions that can impact system integrity and security. By alerting users when an application attempts to install, UAC empowers them to make informed decisions, ensuring that only trusted software is allowed to install, which helps to prevent unauthorized software from compromising the system.

This notification mechanism is central to UAC's role in safeguarding the operating system against potentially harmful changes initiated by malware or malicious users, providing a layer of defense before such actions can alter system settings. While the other choices touch on important aspects of security management, the primary focus of UAC is to engage the user in the installation process directly, allowing them to grant or deny permission based on their awareness and understanding of the action being taken.
