What is svchost(LocalSystemNetworkRestricted)? Why does it take so much memories?


  • I am using vista 64bit ultimate, english version.
    I just upgrade my computer's memory from 2GB to 6GB.
    However, I notice a new svchost(LocalSystemNetworkRestricted) started automatically that it wasn't there previously with 2GB ram.
    And it takes 119,292 KB memory.
    Why is this happening?

  • I've got one like that too, with 2 GB.  It hosts all the biggie services.  Easy to miss if you've got UAC turned on.  Use SysInternals' ProcMon.exe to check what services are hosted by that instance.

  • What's a UAC?

    I tried.. ProcMon.. somehow I can't find it.

  • I got the same "problem" (is it a bug or a feature?). I noticed its RAM-usage rising to more than 400MB, which I maybe would mind less if I knew what it was for. Well, not really, 400MB is quite a lot of RAM

    Win 7 Professional x64
    AMD 6400+
    4GB RAM

  • ok, this seems to be the superfetch-feature: as soon as I diabled it via system settings -> local services (terms guessed, don't have english Win7), that process ceased to block my RAM. superfetch, as far as I know, is used to speed up the start up of frequently used programs by loading them into your RAM in advance.
