To disable the NCtray icon for all users, click 'Run' from the Window start Menu (On some versions of Windows you will need to type run in the search box located in the start menu) and type 'MSConfig'.

Once MSConfig launches navigate to the 'Startup' tab and uncheck the "vSpace" item (see Figure 1, below). (This isn’t “vSpace” itself. It is only the NCtray application that is launched at user login.)

Click the “Apply” button and NCtray will no longer be loaded when users login.

OBSERVAÇÃO: It will take a reboot for the settings to take effect.

OBSERVAÇÃO: MSConfig retains the NCtray checkbox in case you want to re-enable it at a later date.
