Many programs put an icon in the system tray or notification area for easy and quick access, besides providing some progress indication or notification when needed. But some admins like to hide these items on such devices like Thin Clients.
If you feel that notification system tray area is of no use to use, and you want to recover the bottom right space to make more room for Windows Taskbar, it’s possible to turn off and disable system tray with a simple registry hack.
1) Login as the user that your going to make this change for
2) Open the registry. In Windows XP, click Run and then type regedit and hit ENTER. In Windows Vista, type regedit into Start Search and hit ENTER.
3) Navigate to the following registry key in Registry Editor:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
4) Right click on Explorer, and then select New -> DWORD (32-bit) Value (DWORD Value in Windows XP). Type NoTrayItemsDisplay as its value name.
5) Double click on NoTrayItemsDisplay, and set the value data to 1.
6) Log off and log on again or restart computer to make the change effective.
