Version 4.8 of Citrix Receiver for Windows comes with automatic update functionality which is enabled by default. There are a couple of different ways to control the behaviour of the auto-update feature.
Note: Receiver for Mac 12.6 also has the auto-update ability.
There may be times when you want to disable auto-update, especially on clients where Skype for Business is used with the RealTime Optimization Pack. Since RTME is installed on the client, this component may auto-update and become newer than the RealTime Connector with the risk of cleints entering into fallback mode.

You may also want to use auto-update but adjust the default behaviour. The ways of configuring auto-update related settings is described below.
Things to note
- Outbound proxies must be configured with an exception to the Receiver auto-update Signature service https://citrixupdates.cloud.com and the download location https://downloadplugins.citrix.com
- By default auto-update is disabled on Session Host, Remote PC and VDI VDA machines.
- Auto-update is disabled on machines that have Desktop Lock installed.
- Machines must be connected to the internet for auto-update to work
- Receiver for Web users cannot download the StoreFront policy automatically. You have to add or refresh the StoreFront account manually through Receiver.
The first method is GPOs. Download the Receiver for Windows ADMX templates from Citrix and import them on to your Domain Controllers. Edit/create a GPO and navigate to Computer Configuration -> Policies -> Administrative Templates -> Citrix Components -> Citrix Receiver -> AutoUpdate. You have two configurable settings.
The first setting Set the Delay in Checking for Update can be set to Fast, Medium or Slow. This allows for staged upgrade rollouts. Fast means an update is pushed out as soon as it is available. Slow means the update will be pushed out after it has been available and tested for a period of time. Medium is somewhere in between.
The second setting Enable or Disable AutoUpdate Policy is used to set auto-update to disabled, auto (default) or manual (user checks manually for updates). You can also specify if only LTSR Receiver versions are offered for upgrade and set a defer count. The defer count can be set as a value of -1 to 30. -1 means no limit is set on the amount of defers a user can perform. A value of 3 would allow 3 maximum defers for example. A value of 0 means the remind me later option is not displayed.
The second method is to disable auto-update via command line when installing Receiver. A couple of new switches exist to control the behaviour of the auto-update feature.
- /AutoUpdateCheck – Configure auto-update to be on, off or manual. Values accepted are AUTO, MANUAL and DISABLED.
- /AutoUpdateStream – Control if auto-updates are for LTSR versions only or Current Release versions. Values accepted are LTSR or Current.
- /DeferUpdateCount – Allows you to specify the number of times you can defer an update notification. Values accepted are -1 to 30. -1 means the user can defer any number of times.
- /AURolloutPriority – Specify the speed of which a rollout of an upgrade will be performed. Values accepted are Auto, Fast, Medum and Slow.
