UAC

UAC (User Account Control) is a security system in Windows operating systems designed to manage user rights and protect against unauthorized changes to the system. When an application attempts to perform actions that require administrator rights, UAC notifies the user and asks for their confirmation or password to prevent potential threats.

UAC was introduced in Windows Vista to enhance system security and prevent unauthorized modifications. It helps protect the system from viruses and other malicious software that may try to run with administrator rights without the user's knowledge.

Main functions of UAC

• Protection against unauthorized changes. UAC prevents applications from automatically running with administrator privileges without your consent.
• Request for administrator rights. To perform operations that require elevated rights, an application must receive your confirmation.
• Security settings. Users can configure the frequency of UAC notifications by adjusting the notification level.
