what is .NET Host and why is it absolutely hogging my CPU and multiplying itself

My performance is running really bad because of it, and I'm getting constant lag spikes. Most of the time, I get an absolute abundance of lag. I've tried closing other processes I don't need, but the .NET Host just makes more of itself and kills my CPU. I'm also scared to close it because I don't know if it's important or something.

    Hi, thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today, my timezone is UTC +8.

    I understand the issue you have, there is nothing to worry I am here to help, .NET Host is responsible for all .NET processes and is vital for the operating system, in addition, this issue occurs when there are third-party services that interrupt the system process, in this case, kindly follow the steps below:

    Method 1. Do clean boot:

    A “clean boot” starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program.

    • In the search box on the taskbar, type msconfig and select System Configuration from the results.
    • On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
    • On the Startup tab of System Configuration, select Open Task Manager.
    • Under Startup in Task Manager, for each startup item, select the item and then select Disable.
    • Close Task Manager.
    • On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

    Method 2. Run memory diagnostic tool: The memory diagnostic tool is a RAM test to check if any RAM issues causing the processor to go high.

    • Press Windows key + R then type in mdsched.exe hit OK then restart the device.

    Note: If the issue persists, please let me know the make and model of your CPU as repair or test might be necessary.

    Let me know how it goes and I hope that helps.

    Bernard
