For VDI environments, this means:

  • October 1, 2024 → End of Support (Classic Teams in VDI)

Citrix License Activation Service (LAS): Goodbye License Files

If you’re a Citrix customer and thinking “next week…” right now — understandable. But starting April 15, 2026, file-based Citrix license files will no longer work. This is not a warning; it’s a hard shutdown date.

That means: if you haven’t migrated to LAS by then, you risk real outages (apps, desktops, or features depending on the component and version).

In the following I will give an insight into the menu items System Optimization, Policies & Profiles and Security.

System Optimization, Policies & Profiles and Security

System Optimization

These settings are used to reduce resource usage on the host. They are used to free up resources and make them available for other applications, thereby increasing the user density per host.

While the System Optimization settings are machine-based and apply to all user sessions of a machine, the Process Optimization under CPU Management is user-based.

That is, when a process triggers CPU Spike Protection in user A’s session, the event is recorded and limited for user A only. When user B starts the same process, the behavior of process optimization is determined only by process triggers in user B’s session.
