Citrix XenApp 6 Tuning admx Group Policy for Windows 2008 R2

The new ADMX file for tuning of Citrix XenApp 6 and Remote Desktop Services Tuning Group Policy for Windows 2008 R2 from is here!

I have received a lot of requests to make a new set of GPOs for Citrix XenApp 6.0 and Remote Desktop Services running on Windows Server 2008 R2, as a follow up to the very popular Citrix XenApp and Terminal Server Tuning Tips Group Policy v1.0

There is a lot of tuning in this GPO, I will update it when new tunings are found and post updates to the download section of

I’ve made the GPO in admx format (not backup sets!!!), so that it can work 100% with Windows Server 2008 R2 and the Group Policy Manager. It also integrates perfectly with AppSense and RES, so if you use these User Environment Tools, you can simply import the ADMX file and deploy. Also since the admx file format is in XML it’s also quicker to load than regular adm files.

How to install:
Download -> – Citrix XenApp 6 and RDS Tuning , from the link on this page. (This GPO is in admx file format!)
Extract the zip file down to the c:\windows\PolicyDefinitions – catalog

Please not that the settings is by default turned off, so you need to enable the tunings that you want to take place!

UPHClean is natively embedded into Windows Server 2008 (User Profile Service), so that is why you won’t find it available for download anywhere.

Also, another Best Practice, is that I recommend that you Disable Data Execution Prevention on Windows Server 2008 R2.

Here is how you can do that:

Warning! you have to use the following command line to disable it

  • bcdedit.exe /set {current} nx AlwaysOff
