Final answer:
When a user logs on to Windows 10 with UAC enabled, the system issues a security prompt asking for their permission to perform certain actions or make changes. UAC helps prevent unauthorized access and protects the system from malicious software.
Step-by-step explanation:
When a user logs on to Windows 10 with UAC (User Account Control) enabled, the system issues a security prompt to the user, asking for their permission to perform certain actions or make changes that could potentially affect the system. This prompt helps prevent unauthorized access and protects the system from malicious software.
For example, if a user tries to install software or make changes to system settings, UAC will display a prompt asking the user to confirm their intention. The prompt typically includes information about the action being performed and allows the user to either accept or deny the request.
By using UAC, Windows 10 ensures that users have more control over what actions are taken on their computer, reducing the risk of unintentional or unauthorized changes.
