User Account Control (UAC) is designed to prevent unauthorized changes to Windows.

When an action requires administrator-level permissions, UAC prompts you to approve or deny the change. This helps protect your Windows device from malicious software and unauthorized modifications.

You can change the UAC behavior by opening the Control Panel > System and Security > Change User Account Control settings.

Move the slider to your desired level of notification and select OK to save your changes.
