    svchost.exe (netsvc) takes 25% of the cpu :((


    Hello,

    From this morning my cpu is constantly at 27-25% at idle whereas before it was 0 to 3%...It's the very first time something like that happens at idle...I didn't install anything yesterday or taoday (yesterday was fine)..

    i checked the ressource monitor and indeed, it shows that svchost.exe (netsvc) takes 25%...

    I tried to look up the services in task manger and it shows several : Aelookupscv, Appinfo, Browser, EapHost ,gpscv, Lanmanserveriphlpsvc, Profsvc, Schedule, SENS, ShellHWdetection, Themes, Winmgmt, wuauserv.

    Maybe i should disable one of the process to see which one is the culprit?

    I will try to do a malwarebytes scan (((

    any ideas? maybe it is winodws update? I sad

    Thank you for your answers

    well disabling wuauserv (windows update) made the cpu back to normal...any idea what should i do?

    Winodws update wasn't looking for updates when it was at 25% i'm pretty sure of it so idon't know what would cause it.

    i think i'm going to do a thread on the windows update page since it would seems the problem comes from here.

    Hi,
    See if these updates are installed if not manually install them
    When manually installing updates you need to switch your update settings to Never check for updates and restart the machine first.
    Main download page for KB3168965 all versions,

    Then lastly manually install this one,

    After switch your windows update settings back to what you had prior and manually check for updates and the rest should show up shortly.

I am curious concerning what this is. When viewing task manager for "All Users", I see this process using almost 50% of physical memory. It appears twice....one using over 200,000K and a second time at 16,000K. Thanks in advance for the help.
