A process called Service Host: Local System is using up all of my laptops resources

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?

    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!

    Something to note - I was experiencing a similar issue (CPU usage from service host was over 70%), but I noticed the process below it was an HP help process. I ended that, and my service host usage immediately dropped to 0%. Try closing superfluous HP processes and see if it does the trick. 

    I've read through this entire topic.  I'm running Windows10 and having problems with

    scannow found nothing and WindowsUpdate cannot be disabled (although it's a good idea to disable its file sharing process.)

    My symptoms are that the network restricted group of processes grow gradually until they consume all of memory.  After about 4 days, the total private memory allocated to them is the largest of all processes and it continues to grow until other processes can no longer start due to resource limitations.

    I did discover an HP driver process that was hogging the computer and have uninstalled my all-in-one to see if that helps.  Maybe now I can stop having to reboot every few days.

    BTW, my computer does not sleep since I run a Distributed Computing project that keeps it busy 24x7.
