Windows 10: Fix high cpu usage caused by diagnostic policy service

Hello,

as mentioned in another thread reply I found a solution by someone for this common problem with high cpu usage by a windows service. In the folder "C:\Windows\system32\sru" are constantly created log files and the directory becomes very large over time. Then I stopped the service, I even needed to force kill the process via taskmanager because the service was too busy *Smile The service is part of the svchost process structure so you first need to find the corresponding PID of process. It is much safer via cmd and then "sc stop dps". Then you can delete the whole folder C:\Windows\system32\sru. When you start the service afterwards the folder stays empty or even gone. For me it did not affect the service, troubleshooting does still work and cpu usage is now low *Wink

I attached a Batch which finds the pid of the dps service and stops the service. The it promps the user to delete the folder "sru" and starts the service after that.

You can also use the code below and paste it in a new text file. Then rename suffix from *.txt to *.bat and run with admin privileges. *Smile

Code: @echo off echo ... Set DPS service start type to manual ... echo. sc config DPS start= demand echo. echo ... Find PID of DPS service ... for /f "tokens=2 delims=[:]" %%f in ('sc queryex dps ^|find /i "PID"') do set PID=%%f echo. echo ... Kill DPS service echo. taskkill /f /pid %PID% echo. echo ... Delete sru Folder ... echo. rd /s "%windir%\system32\sru" echo. echo ... Set DPS service start type to auto ... echo. sc config DPS start= auto echo. echo ... Start DPS service ... sc start DPS echo. pause[/quote]

Diagnostic Policy Service - high CPU


HP laptop problem
In the last few days, this laptop started having poor performance, with Task manager showing Diagnostic Policy Service taking up to 30% or more of CPU.

HP Spectre x360 - 13-4197dx (ENERGY STAR)




In the last few days it started having poor performance, with Task manager showing Diagnostic Policy Service taking up to 30% or more of CPU.





Did upgrade of BIOS, no improvement.
Downloaded all current windows upgrades – no fix.
I created a new (admin) user, same problem.
I ran all of the diagnostics in the HP Support Assistant, all passed – no effect.
I ran "sfc /scannow." and "Dism /Online /Cleanup-Image /RestoreHealth" – no effect.

There is an online thread on this in the HP forums, which does not seem to show any fix.

The HP support is abysmal – it took several minutes for him to echo back “so this is your computer system?”, and then the only suggestion was a factory reset.

 

Service Host: Diagnostic Policy Service high CPU & memory usage AND keyboard blocked - Windows 10

I have a Surface 3. About 1/24/2018 it downloaded some updates and became unusable most of the time.

The error state includes

diagnostic policy service cpu usage high (was a .exe file)

keyboard is mostly blocked (timed out ?)

mouse partly blocked (computer busy)

the start menu will not show.

4/29/18 got another update, and now shows servicehost having 25%cpu & 827mb ram for diagnostic policy service; the keyboard is mostly blocked, mouse partly blocked (computer busy), and the start menu will not show.

I ran an admin command prompt, but keyboard input was mostly blocked

So I createe an admin command prompt shortcut that ran SFC /scannow using the /c"command"/k command line switches. It was OK.

Any suggestions?
