Windows User Account Control (UAC) is a core security feature introduced in Windows Vista to prevent unauthorized changes to the operating system. It ensures that applications always run under a limited “standard user” context until an administrator explicitly grants permission.
Depending on your exact context, you may be referring to the built-in Windows UAC settings interface, or a specific legacy third-party management utility. 1. Built-in Windows UAC Settings (The Native “Manager”)
Windows includes a native settings panel where users can adjust the frequency and severity of UAC prompts.
How to open it: Open the Start Menu, type uac, and select “Change User Account Control settings”. The 4 Security Levels:
Always Notify: The highest security level. It prompts you whenever apps try to install software or make system changes, or when you modify Windows settings.
Notify me only when apps try to make changes (Default): Windows freezes your screen and prompts you only when third-party applications attempt modifications, but not when you change settings yourself.
Notify me only when apps try to make changes (Do not dim my desktop): The same as the default level, but it does not use the isolated “Secure Desktop” mode. This is less secure against malware scripts.
Never Notify: Completely disables UAC prompts. Apps can silently gain administrative control, which greatly lowers system security. 2. The Third-Party “Windows UAC Manager” Tool
