Upgrading the Horizon client
There is no built-in method to upgrade Horizon clients automatically, and you also need to bear in mind that Horizon clients are on a different release cycle to the main Horizon infrastructure solution.
If you are running thin clients as end-user devices for your users, the upgrade procedure is usually easily managed with the management software that comes with the thin clients.
If you are using re-provisioned PCs, or maybe laptops, to connect to the Horizon View environment, you are going to need to either manually update the client, direct your users to do so, or use a third-party software deployment tool to complete the upgrade.
