Deferred Procedure Calls and Service Interruptions High CPU and Disk Usage Routines in Windows 10

This is a process that will appear in the Processes tab of the Task Manager and the problem occurs when this entry (or posts as users have reported seeing many of them) takes up a lot of your CPU power.

A deferred procedure call (DPC) is a mechanism in the Microsoft Windows operating system that allows high-priority tasks (for example, an interrupt handler) defer the necessary but lower priority tasks for their subsequent execution. This can go wrong and harm users, so be sure to follow all the solutions we have prepared below to reclaim CPU resources.

Solution 1: reinstall or update your network adapter

If something went wrong with the driver related to the network device that is giving you the error and causing the processes to “Deferred procedure calls and interruption of service routines” wake up with CPU usage, you can fix this problem simply by updating or reinstalling the driver. related to him, depending on the type of internet you are using.

When restarting the computer, it will start searching for drivers when the system boots up and it will install again with the latest version. Good luck.

1. First, you will need to uninstall the driver that you currently have installed on your machine.

2. Scribe “Device administrator” in the search field next to the start menu button to open the device manager window. You can also use the Windows key combination + R to open the Run dialog. Scribe “devmgmt.msc” in the box and click OK or Enter key.

Solution 3: use certain tools to identify the true cause

This solution is very useful to identify the problem, as it can be very difficult to know which device, driver or program is causing high CPU. You will need to install certain tools and the process may take a while, but it is important that you focus, as it may be the last step in solving the problem.

1. First, download the Windows SDK which will contain the required Windows Performance Kit which will contain the tools you will need to continue the process. You can download them for Windows 10 using this link.

1. Find the file you just found in your Downloads folder by default and run the setup program. Select WPT (Windows performance tools) from the list and click Install. Restart your computer to complete the process.

2. If you are a Windows user 10, you can easily locate the command prompt by simply clicking the start menu button or search button next to it and typing 'cmd’ or 'command prompt'. Right click on the first result and choose Run as administrator option.

1. Use the following command to navigate to the Temp folder at the command prompt. Make sure to click the Enter key after typing this text:

cd N-temp

1. Use the following command to start the scan and wait a moment until you see High DPC and Interrupt usage in Task Manager.

xperf -about latency -gateway profile

1. When you notice high CPU usage, stop tracing with the following command:

xperf -d DPC_Interruption.etl

1. This will shut down the process and write the results to the DPC_Interruption.etl file. Click on the start menu and type “Run”. Select Run. A Run dialog will appear. Scribe “% temp%” in the Run dialog box and click the OK button. This will immediately open the Temporary Files folder.

1. Find the file DPC_Interruption.etl and double click on it. Wait until the two passes have finished and navigate to Trace >> Set Symbol Paths and type the following:

srv*C:N-símbolos*http://msdl.microsoft.com/download/symbols

1. Now go to the graphics “DPC CPU usage” O “Interrupt CPU usage” (depending on where you see high CPU usage) and select the interval, right click and select “Load symbols” and then click on the summary table. You may need to accept the license agreement to download the public debug symbols and you may need to wait a bit for them to download.

2. Here you can see the summary of the calls and see the causes of the problem. Can be a controller, A program, a service or something similar. Google the file you see that is causing the problem, see where you belong and point out the problem.

Solution 4: fix the problem with a clean boot

If a third-party app or service often causes system outages, you may want to point it out and disable or uninstall it to solve the problem. Users have reported that the problem does not appear on a clean boot, so you may want to see it for yourself.

If the problem doesn't actually appear on a clean boot, you might want to see which app is causing it by enabling services and startup items one by one and removing them.

1. Use the Windows key combination + R on your keyboard to open the Run dialog, where to write “MSCONFIG” and click OK.

2. Click on the tab “start” and uncheck the option “Safe boot”.

1. In the General tab of the same window, click to select the Selective startup radio button and then click to clear the Load startup items check box to make sure it is not checked.

2. In the Services tab, click to select the Hide all Microsoft services check box, then click “Disable all” to disable user-installed services.

1. On the home tab, click on “Open Task Manager”. In the Task Manager window, on the Home tab, right-click on each startup item that is enabled and select “To disable”. Make sure you don't skip any entries, as even the most legitimate applications can cause software conflicts.

2. After that, you will have to perform some of the most boring processes and that is to enable the startup items one by one and restart the computer. Thereafter, you should check if the error reappears. You will have to repeat the same process even for the Services you disabled in Step 4. Once you locate the problematic startup item or service, you can take steps to solve the problem. If it is a program, you can reinstall or repair it. If it is a service, you can disable it, etc.

SUGGESTION: If none of the methods have solved your problem, we recommend that you use the Reimage repair tool, which can scan repositories to replace damaged and lost files. This works in most cases, when the problem originates due to a system corruption. Reimage will also optimize your system for maximum performance. You can download Reimage by clicking here
