Here's how to Fix Deferred Procedure Calls and Interrupts Service Routines High CPU usage on Windows. Run Avast Driver Updater@ https://www.anrdoezrs.net/click-7952654-14577796 to keep your device drivers up-to-date, easily & effectively.

Here are some steps you can take to fix Deferred Procedure Calls and Interrupts Service Routines High CPU usage on Windows:

1. **Check for updates.** Make sure your computer is running the latest version of Windows and all of your drivers are up to date. You can do this by going to Settings - Update & Security - Windows Update.
2. **Disable unnecessary startup programs.** Startup programs are programs that start automatically when you turn on your computer. Some of these programs may be unnecessary and can be causing high CPU usage. You can disable startup programs by going to Settings - Apps - Startup.
3. **Run a virus scan.** A virus or other malware infection can sometimes cause high CPU usage. You can run a virus scan by using your antivirus software or a free online scanner.
4. **Check for hardware problems.** If you have recently installed new hardware, it may be causing high CPU usage. You can try uninstalling the hardware or updating its drivers.
5. **Reset your computer to factory settings.** If you have tried all of the above steps and you are still having problems, you can reset your computer to factory settings. This will erase all of your data, so be sure to back up your important files before you do this.

Here are some additional tips to help you fix Deferred Procedure Calls and Interrupts Service Routines High CPU usage on Windows:

* **Avoid running too many programs at the same time.** The more programs you run, the more CPU usage your computer will experience.
* **Close any programs that you are not using.** If you are not using a program, close it to free up CPU resources.
* **Use a task manager to monitor your CPU usage.** This will help you identify programs that are using a lot of CPU resources.
* **Keep your computer clean.** Dust and dirt can build up inside your computer and cause it to overheat. This can lead to high CPU usage.
* **Use a cooling pad.** A cooling pad can help to keep your computer cool and prevent it from overheating.
* **Get a new computer.** If your computer is old or outdated, it may not be able to handle the demands of modern software. In this case, you may need to get a new computer.

i. Deferred Procedure Calls (DPCs) are a Microsoft Windows operating system mechanism which allows high-priority tasks (e.g. an interrupt handler) to defer required but lower-priority tasks for later execution. This permits device drivers and other low-level event consumers to perform the high-priority part of their processing quickly, and schedule non-critical additional processing for execution at a lower priority. DPCs are implemented by DPC objects which are created and initialized by the kernel when a device driver or some other kernel mode program issues DPC requests.

Interrupt Service Routines (ISRs) are a type of subroutine that is called by the hardware when an interrupt occurs. Interrupts are events that signal the CPU that something important has happened, such as a keystroke or a mouse click. ISRs are designed to be very fast, as they need to respond to the interrupt as quickly as possible.

DPCs and ISRs are both important parts of the Windows operating system. DPCs allow device drivers and other low-level components to perform time-critical tasks, while ISRs allow the operating system to respond to interrupts quickly.

DPCs and ISRs can sometimes cause high CPU usage. This is usually caused by a buggy driver or hardware device. If you are experiencing high CPU usage from DPCs or ISRs, you can try updating the driver or disabling the device. If that does not work, you may need to contact the manufacturer of the device for support.

ii. System interrupts are a normal part of Windows operation, and they can sometimes cause high CPU usage. However, if you are experiencing high CPU usage from system interrupts, it is possible that a virus or other malware infection is causing the problem.

Here are some things you can do to check for a virus or other malware infection:

* Run a virus scan with your antivirus software.
* Use a free online virus scanner.
* Check for any suspicious programs that have been installed on your computer.
* Check for any unusual entries in your Windows registry.

If you find any suspicious activity, you can try to remove the virus or malware infection yourself or you can contact a professional for help.
