ICT-Hotlist Topic

Microsoft Software Protection

Have one or more Citrix XenApp 6.5 user(s) that receive pop-ups stating Windows is not Genuine?

Windows Activation, Windows is not genuine, Your Computer might be running a counterfeit copy of Windows. Get genuine now. Ask me later


  • Windows server 2008 R2
  • VAMT MAK licensing
  • Citrix XenApp 6.5

When you have the following situation (Checklist):

  • A user reports that he/she receives a popup about Windows not being genuine whilst using software with the Citrix XenApp environment.
  • Check in Citrix AppCenter on what Citrix XenApp server he/she is hosted.
  • Log on to that Citrix server using Remote Desktop Connection or vSphere console. Do you get the same "Windows is not genuine" popup on a black desktop background with the activation window?
  • Log on to your VAMT server and get a new status update for the Citrix XenApp server. (Right click the server name, select "Update Status", "Current credential")
  • The VAMT result value must be "Successfully updated the product information."
  • When you receive "Unable to connect" or similar errors, try pinging the server from the VAMT server.
  • Make sure the firewall on the Citrix server is not blocking access from the VAMT server.
  • Make sure the "Software Protection" service is running on the Citrix XenApp Server (start services.msc or type "sc query sppsvc" in a command box)

When all items on the checklist are ticked you can try this solution:

  • Open a command box on the Citrix XenApp server of step 2
  • Enter the following command to stop the service:
    sc stop sppsvc
  • You have to wait until the service stops
  • Enter the following command to start the service again:
    sc start sppsvc
Log on to your VAMT server and get a new status update for the Citrix XenApp server. (Right click the server name, select "Update Status", "Current credential").
You must now get a message "Successfully updated the product information."
When you log off and log on to your Citrix XenApp server again (step 3), the warning must have gone and your original desktop will be restored to notify that licensing is valid again.
