    What does the svchost do?

    Lots of Windows services are tied to the SVChost, and /or are listed as SVChost in the process list(s).

    Unfortunatley with Vista, there's a lot more dependencies between the services, and thus you'll be FORCED to run more instances of SVChosts; unlike XP where things were more independent and you could disable more features resulting in less SVChost instances. That and XP and Vista are different.

    Regardless of your Windows version, you can check out some service slimming guides or goto Black Viper's website and take his advice. Depending on your needs you may be able to cut down the amount of SVChost running, and save some RAM.

    XP should never have an SVChost using 50mb. Vista however can.

    No name service connected to svchost.exe taking up 20-40% of CPU and causing slow downs

    Windows 10 "Service Host: Local Service (No Network)" drains CPU constantly

    I've had this problem for at least several months.
    I noticed a lot of threads without a happy ending:

    1. High CPU Usage from "Service Host: Local Service [...]
    2. Service Host: Local Service (No Network) (3) and Service Host: Internet Connection Sharing (ICS) causing High CPU
    3. svchost.exe Service Host: Local Service (No Network) - Permanent CPU usage
    4. service host: Local Service (No Network) (5) taking up all my CPU resources (i5-4690k)

    And I did try all the suggestions made in these threads including:

    1. Updating the windows to the latest version
    2. Troubleshoot network, update, etc
    3. killing all other software, changing MSISUPPORTED of my SSD disk in regedit etc.

    One thing I noticed is that the problem disappears in safemode.
