Microsoft 365 Copilot taking up excessive CPU on session hosts

Would suggest taking following actions:

1. Identify the High CPU Usage

• Use Task Manager or Performance Monitor on the session host to confirm which processes are consuming the most CPU.
• Check if the high usage is directly tied to Copilot-related processes or other applications like Edge or Outlook.

2. Optimize Session Host Resources

• Scale Up or Out: Increase the CPU and memory resources of your session hosts or add more session hosts to distribute the load.
• Limit User Sessions: Reduce the number of users per session host to prevent resource contention.

3. Copilot Setup

• Disable Copilot for Certain Applications: If Copilot is not essential for all users or applications, consider disabling it selectively.
• Update Microsoft 365 Apps: Ensure all applications are updated to the latest version, as updates often include performance optimizations.
