If you're running RDS on a vSphere server with VMware Tools installed, you may wish to remove/hide the system tray icon. This can be done by setting a certain registry value.

The registry value is:

• Key: HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Tools
• Value: ShowTray

Change the value to 0 will effectively disable the icon the next time a user logs on.
