Workaround after Remote Assistance Error

After installing the January 2026 Microsoft security updates, Remote Assistance (msra.exe) no longer works on multiple Windows versions. This directly affects Citrix Director Shadowing, as the generated invite files can no longer be opened on patched systems.

The issue is caused by a security hardening related to CVE-2026-20824 – Windows Remote Assistance Security Feature Bypass Vulnerability. While the fix is technically correct from a security perspective, it currently breaks legitimate Remote Assistance workflows in enterprise environments.

On October 1, 2024, the Classical Teams client in the VDI context will reach its end of support and, according to the latest news, its end of availability date on July 1, 2025. These end dates have been adjusted several times in recent weeks.

WEM Administration Console – Part 2 (System Optimization, Policies & Profiles and Security)

Current version is Workspace Environment Management 2206.

In the following I will give an insight into the menu items 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.
