Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded. Of the currently active processes, including the names of their owningĪccounts, whereas the information displayed in the bottom windowĭepends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.ĭisplay consists of two sub-windows.
How to find process explorer install#
Install the Debug Diagnostic Tool v2 Update 2.Ever wondered which program has a particular file or directory open? Now you can find out. You can use Debug Diagnostic 2.0 version to further troubleshoot this problem. Data collection Before the problem occurs Now, a scenario: Say you have an external device that you want to eject. Not only will it show you the process list, it will also report back the file handles, DLLs used by different tasks, network and disk activity, and a lot more. If a third-process is identified as the cause of the problem, you must contact the application vendor to understand why the respective process is causing high CPU usage on the computer. This is a super-powerful process management tool, rather similar to Linux lsof.
Record the PID of the offending process by running the following command: To troubleshoot this problem, follow these steps: For example, this problem could occur with the explorer.exe processes on a Remote Desktop Protocol (RDP) server. Several instances of a process could share the same name. Multiple process instances that have the same name Run ProcDump two times during reported high CPU usage. Record the PID of the offending Svchost process.Ĭollect a WPR log while the problem is occurring. Use a 1-second to 5-second snapshot interval. Then, restart the service.Īfter you break each service out into its own svchost process, you now have to identify which service was driving up CPU usage or consuming high CPU usage.Ĭollect a performance monitor log. To do this, replace sc config type= own with sc config type= share in the command. Select the thread that consumes high CPU, and then select Stack to view the functions that are being run.Īfter the problem is resolved, you must return to step 2 and revert what you did.Right-click the process, select Properties, and then select the Threads tab.Run Process Explorer as an administrator.If you want to verify an operating system-related process (for example, System), follow these steps: The Process Explorer tool gives you a complete overview on which processes are currently running on your computer, including details about who invoked the processes, and how much of the total system resources they're consuming. If any of the processes show a higher-than-expected rate of consumption for your environment, consider these top processes first when you try to determine the cause of the problem. Make sure that the arrow that appears on the header points down to sort the data from highest to lowest CPU consumption. Select the Average CPU column header to sort the list by overall CPU usage. You might have to maximize the window to see all the data. In the Resource Monitor window, select the CPU tab. Select Start, enter resmon, and then select Resource Monitor from the search results. Use the Resource Monitor to view CPU consumption: Then, check whether this mitigates the problem. If the process can be stopped, or a related service can be disabled, stop the process or the service. Select the CPU column header to sort the list by CPU usage.If you see a single list of process names in the Name column, you can expand any instances of grouped processes. The Task Manager window defaults to the Processes tab.
However, if you consistently see CPU usage remain at a high level (80 percent or greater) for prolonged periods, the performance of your system or application will suffer. Keep in mind that you can expect CPU usage to increase as a process or an application serves requests. This article helps you identify the cause of sustained high CPU usage.
