The NetScaler Gateway plug-in for Windows now supports two registry values for controlling the visibility of NetScaler Gateway plug-in and client cleanup behavior in the integrated mode of Receiver and NetScaler Gateway. These registry values toggle the client cleanup functionality and the visibility of the NetScaler Gateway plug-in on the system tray. The registry values are available for the Windows plug-in with the NetScaler 10.1 release in the 10.1.129.x builds and in the 10.5 release from the 10.5.52.x builds.

• Enable or disable NetScaler Gateway plug-in cleanup when Receiver for Windows is running.

• Show or hide the NetScaler Gateway plug-in icon that is integrated with Receiver for Windows.

Requirements

• NetScaler 10.1.129.x or later or NetScaler 10.5.52.x or later

• NetScaler Gateway plug-in for Windows version 10.1.129.x or later/10.5.52.x or later

• Receiver for Windows

• Windows operating system

Instructions

To enable client cleanup on NetScaler Gateway and set the registry entry on the user device, edit the following registry values:

Run: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Secure Access Client
Name: AllowCleanup
Type: REG_DWORD
Data: 1

To show the NetScaler Gateway plug-in icon, edit the following registry values:
Run: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Secure Access Client
Name: DisableIconHide
Type: REG_DWORD
Data: 1

Restart the NetScaler Gateway plug-in to enable these changes.

From NetScaler version 11.0 we can decouple VPN plug-in from receiver and display to user without editing the registry entry refer http://support.citrix.com/article/CTX208914 for how to achieve.
