Citrix: The (not so) hidden C: drive caused by XA650W2K8R2X64011

Yesterday I was discussing the Mobility pack with a co-worker on a project and he told me his start menu was changed. After logging into the desktop with my iPad I recognized the mobility pack (which is a good step in new functionality). He was wondering how it got installed so after some investigation he found the reason, he had been installing hotfixes on his system and installed Hotfix XA650W2K8R2X64011 and the readme says:

This release is a part of the XenApp 6.5 Mobility Pack. Documentation for the mobility pack is available in eDocs at To install the mobility pack in its entirety, you must install:

  • Server hotfix XA650W2K8R2X64011.msp
  • Group Policy Management Console hotfixes CitrixGroupPolicyManagement_x64.msi (GPMx150WX64002) and/or CitrixGroupPolicyManagement_x86.msi (GPMx150WX86002)

After installing the GPMC Hotfixes he was able to disable the Mobility pack via policies. One of the stranger things we noticed was that although the C: drive was hidden via policies it could be accessed when using the Mobility pack, I remembered Dennis van Dam saying something like that on twitter and I found the following threat on the Citrix forums  Mobility Pack and Group Policies where other people were having the same experiences but the topic seems to be dead, when there’s an update I will test it and report it back in this blogpost.

    Hi Gabriele,

    The session goes to disconnected, the touchoptomizedDesktop.exe calls a tsdiscon.exe rather than invoking a log off. which is a strange choice by Citrix.

    Could you share that private hotfix you received? or the call reference number?

  2. one question: if you logoff from Touch Optimized Desktop, the session change to disconnect or logoff correctly ?
    this happens in my environment…

  3. There is a private hotfix for this problem, i’ve test and it’s ok! (new TouchOptimizedDesktop.exe)

      Do you have a reference for this private hotfix? Would like to test it too! The environment with the mobility pack installed isn’t mine but I can try to test this next Friday.
