How to Disable Annoying Citrix Receiver Popup

PROBLEM
You install the Citrix Receiver, and you get this annoying setup window each time you start your PC.  You never really configure the client because you only use the web client.

SOLUTION
Open "Command Prompt" as Administrator (right-click, run as Administrator) and run this command:

REG ADD "HKLM\Software\Policies\Citrix" /f /v "EnableX1FTU" /t REG_DWORD /d "0"
