Earlier today in a post titled Minimize Your Running Applications To System Tray Instead Of Taskbar, you will see that TrayIt! allows users to minimize the applications to system tray instead of taskbar. Another great feature of this software is that it allows you to remove icons from your system tray.
The process is pretty easy, quick and straight forward. Open the program, click on Edit and select Shell Icons.
Now you will see a list of programs that are running in the system tray, simply uncheck the box of the program that you want to remove from the system tray and you are done.
