The Pharos Client Tray is removed by deleting the Registry REG_SZ value 'Pharos Systems Blueprint Client Tray' from the following key:
32-bit Windows: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
64-bit Windows: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run
Removing this will not have a negative impact on the Tracker performance. However, a user will not be able to see currently-assigned Print Policies, nor will he or she be able to release Secure Release Here jobs from the desktop (when enabled through the Blueprint Administrator).
