Windows 10: Consistent high CPU usage / svchost.exe Diagnostic Policy Service

Normal/typical size is more like 90-100 MB (just check 3 of my PCs and all were in the 97 MB ballpark). You'll be pleased to read that the typical solution to this kind of problem is indeed to delete that file. When it starts growing uncontrollably, seems most likely to be caused by file damage or corruption. Once deleted, it will re-create itself anyway. See this other TF thread for more discussion: Anyone else have this SRUDB.dat error all the time? - Windows 10 Forums.
HTH,

Hello,

For a few days now my office desktop has been pretty much running non-stop a svchost.exe process which is linked to Diagnostic Policy Service and seems to consume approximately 25-30% of my CPU max speed.

While the PC isn't doing much CPU-wise, this process forces the CPU to run at max speed at all times and the fan to become loud as well.

I ran sfc and dism and nothing came back as erroneous. Event logs aren't flooded with any mysterious messages.

This service seems to store a ton of logs at C:\Windows\System32\sru as well, many thousands of them in the last few days.

Any ideas on what might have caused this? Thanks!

:)

 

"Service Host: Local System" taking up every bit of disk space it can get and slowing down my computer. How do I fix this?

Windows 10 Pro - Unistack / Unistore - High Data / CPU Usage

Got the following Problem with my Surface 3 Pro:

Very high writing / reading and cpu usage of the "Unistack service group". Like the following file which is accessed by svchost

svchost.exe 1128 C:\Users\XXX\AppData\Local\Comms\UnistoreDB\store.vol

Ending the processes result in short time with no cpu and data usage at all and then it is restarted and again very high data / cpu usage

 

Couldn't say what's causing it, but there's a couple good tools you can use to do some investigating. They're also free *Smile

Process Explorer - Windows Sysinternals | Microsoft Docs

Also, you can have VirusTotal check the processes running to see if anything is suspicious or infected.

To do this, launch the program, click on Options / VirusTotal.com / check the space next to VirusTotal.com. Agree to the terms & the results will show up in the VirusTotal column

Hope this helps you out.

 

For reference, I deleted the srudb.dat file in /system32/sru and the problem went away. It had become a 16GB file for some reason...seems alright now.
