In vSphere Client 4.1, it is documented that to disable the Getting Started tab of VMs, you go to Edit -> Client Settings and untick Show Getting Started Tabs as noted below:
Disable Getting Started Tabs
You can disable the Getting Started tabs if you do not want to display them.
Procedure
However, mine was already unchecked – so I checked it, clicked OK, then went back into settings and unchecked it.
NOW the Getting Started Tabs are disabled. =)
