During the investigation, it was observed that the “Animation effects” setting in Windows was either disabled or being reset during the ICA session.
To address this, we used guidance from the following resources:

• Registry key to turn on "Show animations in Windows"
• CTX205067 – How to prevent wfshell.exe from overwriting user settings

These references were used together for the following purposes:

• The Microsoft guidance explains how to enable the required Windows setting for animations.
• The Citrix article explains how to prevent the wfshell.exe process from overriding or resetting this configuration during session initialization.

Without addressing both aspects, the setting may revert even after being manually enabled.

To ensure animation effects are properly enabled within the ICA session, please follow the steps below:

1. Launch a Citrix ICA session
2. Navigate to:
   Settings → Accessibility → Visual effects
3. Turn ON the option:
   “Animation effects”

Additionally:

• Apply the configuration described in the Microsoft article to ensure the setting is properly defined at the OS level.
• Implement the guidance from CTX205067 to prevent wfshell.exe from overwriting the setting during session start.

By combining both configurations, the setting should persist consistently within ICA sessions.

Users reported that animation effects within Citrix ICA sessions were not enabled, even after being configured. The setting appeared to revert automatically, impacting the user experience within the session.
This behavior was identified as being influenced by a combination of Windows configuration and Citrix session handling.
