Vern wants to know  “What is ActionUriOOPServer?”

cortana-internet-explorer

I will assume you saw this on your task manager in Windows 10. This is a process you’ll see associated with Cortana in Windows 10.

Since Cortana does and knows a lot of things, you’ll sometimes see multiple processes running.  If you find that your PC is slowing down, you can disable Cortana and see if that speeds things up.
