Why do I get a User Account Control (UAC) message in Vista/Windows 7?
In order to provide access to actual protected directories and files in Vista and Windows 7 (rather than virtual copies of these directories and files), applications like ZTreeWin must request access every time they run. ZTreeWin requests the highest level privilege elevation available to that user. If the highest level is administrator, Vista requires the user to confirm this elevation with this UAC dialog (even though the user is already logged in with administrator privileges). The alternative is to disable UAC, which removes this malware protection entirely.
