Those are not UAC related icons. Those are third-party applications but if you like to remove the message/pop up box when you open the programs:
To disable the UAC, enter the Control Panel and type UAC in the search box.
The first result returned by the search will be User Accounts – Turn User Account Control (UAC) on or off.
Click on it and the UAC window will open. Deselect the option Use User Account Control (UAC) to help protect your computer and press the OK button.
Windows Vista will ask you to restart your computer. After the restart, UAC will be disabled and all the confirmation requests will no longer bug you.Source.
