My laptop has been running very slowly for the past few days which is weird because my laptop is quite powerful and has always run very fast. I looked at my task manager and saw that a process called Service Host: Local System was using up almost all of my RAM. I am running Windows 8 Pro on a Sony VAIO S13P. What can I do to fix this problem?

    I have similar issue using Win 10 with AVG. Stopping AVG does not solve the problem. I've also run the scan to check Win 10 and that's fine - no problems found. I', pretty sure it service host itself. I can hardly bear to use my OPC anymore, I keep borrowing my wife's Win 7 oldie - which speeds along (also has AVG)

    HELP

    Changing my "check for windows updates" to "never" worked! Now I just have to figure out why checking for updates was using up so much CPU.

    I have tried all 3 methods several times now, yet the machine is still not running well.  "Service Host: Local System (16)" is consistently sucking up 60% or more of the CPU.  In addition, I cannot successfully run Windows Defender - when started it just continues running without completed an update. 

    Device Information:

    HP Stream [2GB memory; 64-bit OS, x64 based processor: Intel Celeron N2840] running Windows 8.1

    Microsoft Defender; no other security applications; several scans using Defender have been completed

    Machine is up to date on Windows

    Laptop is not running any applications

    Please help!
