A small red recycle icon shown at the system tray indicates that there are files in your Recycle Bin and if there is a green icon, it means your Trash is empty. Just double click (or right click) to empty the trash.
Click Start button - Control Panel - Appearance and Personalization - Personalization. In the left pane, click Change desktop icons.
To remove the Recycle Bin from the desktop, uncheck the Recycle Bin check box. (Check it to display the Recycle Bin again). Click OK to save the settings.
