    Service Host- Local Session Manager using too much memory

    My Dell 7010 Desktop recently always showing :

    Service host local session manager is using so much CPU, what do I do? FIX-Your-Computer-Is-Low-On-Memory-Warning-In-Windows-10.png

    I have 12 GB memory which was updated from 4 GB since this warning first time coming. After updated, Warning still coming. I checked the Task Manager and find Service Host- Local Session Manager always using too much memory. Who can give me a suggestion?
    Please!!

    Local Sessions Manager

    Hi Carol,

    Thank you for writing to Microsoft community forums.

    Did you make any changes on your computers recently?

    Are the computers on domain?

    Do the computers boot to desktop or get stuck at
    "Waiting for Local Session Manager" screen?

    Local Session Manager (LSM) is a Win32 service, which starts automatically when the operating system starts. It is a core Windows Service that manages local user sessions. Stopping or disabling this service
    will result in system instability.

    Local Session Manager cannot be started if the following services are disabled, deleted or working improperly.

    DCOM Server Process Launcher.

    Remote Procedure Call (RPC).

    RPC Endpoint Mapper.

    To help you better with this issue, please get back to us with answers to the questions listed above.

    Service host local session manager is using so much CPU, what do I do?

    svchost.exe / service host : local system ( network restricted ) high usage memory and CPU

    When you open Task Manager a little bit, you’ll see that svchost.exe service host: local system (network restricted) is causing the problem of high CPU usage. To improve your Windows performance, and get rid of the high CPU usage, you
    have to disable Superfetch service. Superfetch used to pre-load data from hard disk into RAM memory. So let's follow this steps.

    Fix svchost.exe service host: local system (network restricted)
