    So, it starts when I start development server from npm. And continues till next restart even when I shut down the server. And my CPU runs at 100% usage.
    Why is this? And how do I fix this?

  2. High CPU usage: Service Host: DCOM Server Process Launcher


    So for quite a while now, I have been having issues with my pc.
    After using it for a couple of hours (playing games, browsing the internet, using it for university work, etc.) its performance is noticably lower than just after startup. Task Manager tells me that

    svchost.exe Service Host: DCOM Server Process Launcher

    is using about 25% of my CPU and 30% of my RAM. This seems incredibly high to me. Restarts solve the issue but I would rather not have to of course.
    I've googled the problem already, but a lot of forum posts are from people using Windows 7 or are unsolved.
    Standard Microsoft procedure has you using RAM checkers and all that. I did that, and the results were that my RAM is fine.
    It is also not Windows update sharing as some suggest as I have that turned off.
    I'm really hoping someone can help me here.

    service host DCOM server process laucher high CPU usage

    Same in my Windows 10 for a long time.

    Recently, I used the process monitor (remember to click file-show details for all processes) from Windows Sysinternals suit to check the DCOM server process launcher process (svchost.exe). I found a System Events Broker server thread with start address
    “DAB.dll!DabSessionStateChanged+0xe4c” use a lot of CPU and make a lot of cycles delta(ten times than others)record. After suspended this thread, the DCOM server process launcher seems works fine, no more high CPU usage. I don’t know is there some side effects
    to suspend the thread or is it the same dll cause this problem in another computer.

    Although I had to do this every boot, it`s really a workable temporary solution for me.
    Hope MS fix it as soon as possible and this is helpful.

    Service Host: DCOM Server Process Launcher High CPU Usage (100%)

    service host DCOM server process laucher high CPU usage

    Same issue, DCOM launcher triggered high CPU usage on our WINDOWS 2012 production server. The server seems to be OK after the restart but it is difficult to reboot the server during the production hours. It seems like no fix is available from Microsoft.
    I'm looking into how to prevent this from happening again.

    Thanks
