Windows 10: Slowdowns and Crashes from Service Host: Diagnostic Policy Service

Hello,


I'm running Windows 10 on my desktop and I have recently been getting huge slowdowns due to the Service Host: Diagnostic Policy Service process. I can force quit the application, which restores normal system function for 10-15 minutes before it slows down again and I have to once again end the Service Host.


I have tried doing a clean reinstall of Windows 10 but the problem persists. I suspect the source of the problem is with the hard drive itself slowly failing. I have tried to clone the partition containing my OS onto another drive, but my computer crashes during the cloning process. Any thoughts on how to proceed?

Thank you!

:)

 

The Diagnostic Policy Service is not running

Hi,

To resolve this issue, launch the command prompt as Admin and enter
these:

• Type " net localgroup Administrators /add networkservice " then press Enter.
• Type " net localgroup Administrators /add localservice " then press Enter.

Also, we need to make sure that the following services are started.

1. Press Windows key
+ R.

2. On the dialog box, type services.msc

3. Under Services (Local)
list, find the services: Diagnostic policy, Diagnostic Service, Diagnostic system host.

4. Check the status of the services is started or not.

5. If the services are not started, you can
Right Click a status and Start a service.

6. Restart your computer.

Please post back with the result for further assistance.

 

Disabling Diagnostic Policy Service


I just disabled the Diagnostic Policy Service, Diagnostic Service Host, and the Diagnostic System Host.

Is there any adverse actions that this may cause? So far I have not noticed any.

Once I get my Windows Settings the way I like, they normally stay the same, as I do not do any updates.

Thanks.

 

Consistent CPU Usage by Service Host : Diagnostic Policy Service


Hello Guys,

I'm using Windows 10 Home Single Language 64-bit. After the latest Windows update in Feb 2018, I've been experiencing consistent CPU Usage (13-14%) by a Windows Process (Service Host: Diagnostic Policy Service).

I can't figure out why is this process taking CPU usage every time even when the system is idle. *Huh

I tried to limit its startup, by changing its startup type to Manual, but this went in vain.

A screenshot has been added to make it more clear.



Any tips or tweaks regarding this?

Thanks
