| From the vSphere Client, go to Administration >> Solutions >> Client Plug-Ins, click the radio button next to the unknown plug-in, and click "Disable". |
If the plugin will not be needed in the future, proceed to uninstall the plug-in.
To uninstall plug-ins, do the following:
If vCenter Server is in linked mode, perform this procedure on the vCenter Server that is used to install the plug-in initially and then restart the vCenter Server services on the linked vCenter Server:
In a web browser, navigate to "http://vCenter_Server_name_or_IP/mob", where "vCenter_Server_name_or_IP/mob" is the name of the vCenter Server or its IP address.
Select and copy the name of the plug-in to be removed from the list of values under "Properties".
Click "UnregisterExtension". A new window appears.
Paste the name of the plug-in and click "Invoke Method". This removes the plug-in.
Close the window.
Refresh the Managed Object Type:ManagedObjectReference:ExtensionManager window to verify the plug-in is removed successfully.
Note: If the plug-in still appears, restart the vSphere Client.
Note: The Managed Object Browser (MOB) may have to be enabled temporarily if it was disabled previously.
