Windows System Tray Software
There are several applications out there that can move almost every open window from the Windows Taskbar to the Windows System Tray. Tray It is one of the more popular applications. It is portable, comes with a clean interface and does the job flawlessly. Tray It remembers settings and the only downside of using it would be the resource usage of it.
If you are running low on system resources you could use the windows system tray software Trayconizer instead which uses roughly half of the system resources of Tray It mainly because it completely manages to do without an interface. Trayconizer is a command line driven application that can be best used by creating shortcuts that point to the applications that should be placed in the Windows system tray when minimized.
Trayconizer is portable as well and uses a little bit more than 10 Kilobytes of hard drive space. The user can use the following command line parameter to move the selected application into the Windows System tray when the user minimizes it.
/path/to/trayconizer.exe "path/to/application". For example c:\trayconizer "d:\apps\firefox.exe". Trayconizer makes use of one additional parameter -minimize which when used starts the application minimized in the Windows system tray.
The easiest way to work with Trayconizer would be to create a shortcut to Trayconizer. A right-click on the shortcut and the selection of properties makes it possible to add the "path/to/application" to the Target form field. A click on the shortcut would then launch the desired application normally and would minimize it to the Windows system tray when minimized.
Update: Try It is no longer available, the website returns a 404 not found error when you try to open it. I suggest you use Trayiconizer instead which is still working under recent versions of the Windows operating system system. The portable program has a size of only 10 Kilobyte, and while you need to use shortcuts to add programs to the system tray when you minimize them, it may very well be worth it if you need some programs to minimize to it and not the taskbar.Advertisement
