    Service Host: Device Association Service Causing RAM usage spike


    In reference to this question here, I have more information to add to it. Yes, the question is from a few years back, but I had come across this a few times recently with customers that I work with.In my customer's case, it was not causing CPU usage spikes, but more RAM usage spikes. This was caused from a USB Bluetooth adapter we had installed for her last year so she could connect a set of Bluetooth headphones. Today, she was experiencing slowness issues with her PC and after some digging, I found that this process: Service Host: Device Association Service was using about 50% to 55% of 1GB o

    Insane RAM spikes from Service Host: Diagnostic Policy

    I have a laptop with an i3-7100U and 8GB of DDR4-2133 (upgraded from the original 4GB) RAM.


    For some odd reason, even if I have NOTHING open, Service Host: Diagnostic Policy Service constantly keeps changing its RAM usage, from barely anything to an insane amount. My "Performance" tab in Task Manager looks like this:



    Service Host: Device Association Service Causing RAM usage spike 257128d1575067366t-insane-ram-spikes-service-host-diagnostic-policy-ram-issues.png


    Notice how the RAM usage keeps spiking. This will honestly continue for as long as I have the laptop turned on.

    The RAM that I installed to replace the original 4GB of RAM is the exact same speed as the factory original.

    And yes, if I disable the Diagnostic Policy Service in services.msc, it does stop the spikes. But I shouldn't have to do that every single time I turn on the computer. Also, I've already reinstalled Windows 10 with a fresh install (yes, that's how much it bothered me) but it didn't fix the issue.


    Any ideas? I'm starting to think it's an issue with a Lenovo driver I might have installed, but I'm not sure.

    service host local system cpu usage spikes

    Periodically my chrome browser freezes. After attempts to fix chrome failed, I noticed that the service host local system cpu usage spikes to over 60%. What should I do?

    Service Host Diagnostic Policy Service causes RAM usage fluctuations

    As stated above, this problem started after installing the newest update (Version 1903). This keeps making my PC lag due to the high RAM use. I looked into task manager and found that Service Host Diagnostic Policy Service was causing the fluctuations
    in RAM usage.

    Attached is a screenshot of Task Manager showing the RAM fluctuations
