Citrix XenApp and Windows Server 2016 – Optimisation Script

The following details the Computer Settings that the script will perform in order to Optimise Windows Server 2016 in XenApp/RDS based environment as per citrix optimisation Guide in 2008 R2/Various blogs and my own experience in running citrix environments.

I have extensively reviewed all settings/Changes and believe that they all apply to Windows Server 2016 (from server 2016 performance tuning, validated services/tasks) but please feedback any mistakes…

      • Further review, it is because there is a .EXE for the Set-ACL element of the script. I have tried to password protect but same issue occurs. Send me a mail on david@wilkyit.com and i’ll try and send via that.

    • try that again now. I have renamed the .bat & .exe to .txt to get around the wordpress restriction. When extracing files ensure that
      RemoveQuickAccessandNetwork.txt is renamed RemoveQuickAccessandNetwork.bat

      and

      Set-ACL.txt is rename to Set-ACL.exe

      Apologies for the issue, hope this resolves getting you access to the script now. Let me know
