How to fix Agent Activation Runtime_15831 high cpu and memory consumption problems


I have a windows 10 notebook, CPU is intel core i7, 16G memory, recently I encountered a computer usage problem, I found that a windowd system service: Agent Activation Runtime and Service Host: Local Service (Network Restricted) consumes high CPU, up to 30%-50%, memory consumption of 3G or 3.5G,I searched it, it related to the Cortana but I had never used it much,this situation has been for several days, seriously affecting the operation of other software, how to fix it?
