How can I move icon from taskbar to system tray in windows 7?

I want to move icons from taskbar to system tray in Windows 7

Option 1: Tray Everything (free):

TrayEverything is a lightweight portable application that minimizes windows to the system tray even when the program lacks native support for being parked in the tray.

In addition to simply minimizing windows to the tray, TrayEverything also has options to add a button to the title bar of windows for minimizing to the tray, hot keys to minimize, and even using inactivity as a trigger to send a window to the tray.

If you'd like to keep a program running but don't need to tend to it or would like to make sure nobody messes with it, TrayEverything can minimize it without a visible icon in the tray and even password-protect it.

For more system tray goodness, check out Trayconizer a program that starts your program in the system tray from the moment it's run.

TrayEverything is a free download for Windows only.

Option 2: Trayconizer (free):

Freeware application Trayconizer turns any application into a system tray application in just a few steps.

Unlike other previously mentioned minimize-to-system-tray apps like TrayIt or 4t Tray Minimizer, Trayconizer starts applications in the system tray from the moment you run them.

To use it, you need to tweak the shortcut you're using to launch the application (right-click shortcut and select Properties) by adding the path to Trayconizer in front of the app like so: C:\Path\To\Trayconizer.exe C:\Windows\Notepad.exe.

Trayconizer is freeware, Windows only, requires no install, and consumes a paltry 2MB of RAM.
