How to Fix Service Host: Diagnostic Policy Service High CPU & Memory Usage

If you’re noticing that your computer’s CPU and memory usage is spiking when you open the Task Manager, it’s likely that the Service Host: Diagnostic Policy Service is the culprit. This process is part of Windows and is responsible for checking for system problems and applying repairs.

Unfortunately, the Diagnostic Policy Service can sometimes start using up a lot of resources, causing your computer to slow down. If you’re seeing this happen on your machine, here are a few steps you can take to fix it.

First, try restarting your computer. This will often fix the problem, as the Diagnostic Policy Service will be reset and won’t be able to start consuming high amounts of resources again.

If that doesn’t work, you can try disabling the service altogether. To do this, open the Services window (you can search for it in the Start menu). Find the entry for Diagnostic Policy Service and double-click it. Change the Startup type to Disabled and click OK.

Of course, this means that you’ll no longer be able to use the Diagnostic Policy Service to check for system problems. However, if you’re not having any issues with your computer, you probably won’t need it anyway.

If you want to keep the Diagnostic Policy Service enabled but want to prevent it from using too many resources, you can try changing the way it works. Open the Registry Editor (again, you can search for it in the Start menu) and navigate to the following key:

If this key doesn’t exist, you can create it by right-clicking on the Windows key in the left-hand pane and selecting New > Key. Name the new key {9C4A4A8F-2E97-45D2-97BC-4DF5DFC3BB5E}.

With the key selected, double-click on the DWORD value named DisablePerformanceCounters and change the value from 0 to 1. This will prevent the Diagnostic Policy Service from collecting performance data, which should in turn reduce its CPU and memory usage.

You may need to restart your computer for the change to take effect.

These are just a few solutions that can help fix the Service Host: Diagnostic Policy Service high CPU and memory usage issue. If you’re still having trouble, you may need to contact Microsoft support for further assistance.
