User Account Control (UAC)
What is UAC?
User Account Control (UAC) is a security feature introduced in Windows Vista and present in all subsequent versions of Windows. Its primary purpose is to reduce the potential impact of malicious software by limiting the privileges of standard user accounts.
How does UAC work?
UAC works by displaying a prompt whenever a program or action requires administrative rights. This prompt asks for confirmation from the user before allowing the program to proceed. By default, UAC is enabled in Windows and prompts are shown when installing software, changing system settings, or modifying critical files.
Configuring UAC Settings
To configure UAC settings, you can follow these steps:
- Open the Control Panel and navigate to the “User Accounts” section.
- Click on “User Accounts” to open the User Accounts settings.
- From there, click on “Change User Account Control settings” to access the UAC settings.
- In this window, you can adjust the UAC level using a slider, ranging from “Never notify” to “Always notify.”
- Select the desired UAC level and click “OK” to save the changes.
By modifying the UAC level, you can balance the security of your system with the convenience of using certain applications that may require administrative privileges.
UAC in Different Versions of Windows
While UAC was introduced in Windows Vista, it has evolved with subsequent versions of Windows to provide increased security. In Windows 7 and Windows 8, UAC prompts can be customized to show fewer notifications, reducing user interruptions. Windows 10 further enhances UAC by including new features like virtualization-based security and Windows Defender SmartScreen.
