Answer

The WorkloadsSessionHost.exe process is a system component in Windows 11 (Copilot+ PC).It is part of the Windows AI infrastructure (Windows AI Fabric) and is primarily used to support AI features such as Copilot, Recall,Live Captions,semantic search,and image recognition.



When the system has enabled or is using related AI features,multiple WorkloadsSessionHost.exe processes may remain running in the background to preload AI models.This process is part of Microsoft's system mechanism and cannot be closed by manually selecting End task.As a result,you may see multiple WorkloadsSessionHost.exe processes consuming memory,with memory usage fluctuating in real time.
