On the screen that's summoned, select "Task Manager" at the bottom.
At the top of the Task Manager, click "Performance."
Quick tip: If you don't see this option, your Task Manager might be in "Fewer details" view — click "More details" in the bottom-left to reveal all the options.
In this menu, click "CPU" in the left sidebar. You'll see a graph showing your CPU usage over time, and you can find your current usage listed under "Utilization."
The CPU usage, as seen via the Windows Task Manager.
