Disabling Copy & Paste in PCoIP

As organisations move to PCoIP for a richer end-user experience they start to face configuration dilemmas when trying to simulate RDP existing features. One that I have been asked few times in the last month or so is about Disabling Copy & Paste in PCoIP.

It is possible to disable copy/paste changing the virtual channel configuration. VMware has integrated PCoIP protocol into the VMware View Client and the View Agent while still providing backward compatibility for RDP and RDP virtual channels.



The solution is rather simple. Use the PCOIP.ADM template and create a new GPO. Then set the following:

Computer Configuration –> Admin Templates –> PCoIP Session Variables –> Not Overridable Admin Settings –> Virtual channels Set it to Enabled and enter the unauthorized virtual channel list: mksvchan

Optionally, add the following key into Windows HKEY_LOCAL –> SOFTWARE –> Polices –> Teradici –> PCoIP–> pcoip_admin –> pcoip.vchan_unauth_list –> mksvchan

    I would you recommend to create the registry entry via GPO. If you are creating the registry entry manually you need to make sure the GPO is not going to overwrite the registry entry with the opposite option.

    The registry should be set to mksvchan. This is the name of the channel to be disabled.

    I am trying to install the key mentioned above. Just to confirm, none of the string exists. What value needs to be put in the default?

    Thank you for any information

  2. With the latest versions of the ADM you simply need to check, “Disable clipboard processing on PCoIP host” and enable the policy. You no longer need to specifically add in the mksvchan string.

    Does anyone know the name of the other virtual channels used by PCoIP?

  1. […] Don’t forget what PCoIP looks like from a stack perspective. To get a quick look at what the PCoIP network stack looks like, check out this article that Andre Leibovici,wrote on disabling the clipboard transfer with View, there is a great graphic on there that highlights how it’s broken down. http://myvirtualcloud.net/?p=927 […]
