I have just installed Windows 11 25H2 with the new Ryzen 9 cpu. I notice that there is a near constant use of the NPU even while the machine is idling, between 60-95%. It appears that several processes named “WorkloadsSessionHost” are the likely culprits, but I’m not sure if this is of much help. I’m not using windows copilot, nor do I have any VMs running. I’m not sure what else to look at to determine where this usage is coming from. I’ve tried letting the machine sit for 30 minutes to see if whatever task is driving this usage would come to an end. No luck.
Is anybody else seeing this behavior?
