85% Processor Usage while idle

My Microsoft Surface Pro 4 has recently started showing high CPU usage even while I’ve got nothing running in the foreground.

It’s annoying because I’m used to the idea of lower CPU usage being related to extended battery life, and if the CPU is being used by an unnecessary program, I’ll stop using that program.

The other interesting thing is that Microsoft Edge is showing as a significant user of both CPU and Memory. I’ve not yet launched Microsoft Edge since I told the operating system to restart.

Is this some placeholder in the Task Manager?

If I run the Sysinternals Process Explorer side by side, it shows the machine being very lightly used, which is closer to what I expect to see from task manager. If I want real information on what’s going on with my computer I’m more likely to use the Sysinternals tool, but the task manager is already installed on all windows machines, and has some simple graphs to look at, including watching network traffic.
