It shows the CPU usage, CPU time, and the number of active threads for each process. You can check the CPU usage by expanding the CPU.

First, open the Resource Monitor using the steps below: The Resource Monitor offers more detailed information on CPU utilization. Logical processors are the virtual cores your system uses after hyper-threading the physical ones. Clicking on CPU shows the graph for its activity along with details on usage, active processes, and threads.Īlso, right-clicking on the graph and selecting Change graph to > Logical processors shows the CPU activity for all logical processors. You can also check the total CPU utilization for the last minute from the Task manager’s Performance tab. So, if its value is very high, your system is using only a small percent of the CPU processing capacity to run active processes. The System Idle Process shows the free processor time on your PC. So, if a process runs for 2 hours while using 50% CPU, its CPU time shows 1 hr. And the CPU time shows the total processor time a process has been using since its launch.ĬPU time of a process = Process uptime * CPU utilization of the process. The CPU column shows the CPU usage across all cores for individual processes.

The Task Manager is the most common program to check CPU usage. But you can also use command-line interfaces such as PowerShell. Most users often use GUI tools such as Task Manager or Resource Monitor to check CPU usage on Windows OS.
