Windows service host using 100% of cpu randomly RRS feed

  • Question

  • I have noticed that seemingly randomly my computer will grind to a complete halt and I had no idea why. The problem first appeared when I was watching netflix and it would cause the video to completely halt and for fragmented sounds to play. Later it started to happen even when I was just using my computer to move documents around or browse the internet. I have done a few SFC /scannow and also scanned my computer for various malware with different programs including bitdefender and spybot.

    I have not installed any new programs that I noticed that caused a problem the problem appears to be mainly caused by service host:local service (4). I stopped windows from auto updating but the problem still persists so I re enabled it. Any help you could offer I would greatly appreciate.

    Ps: I remember reading about this being caused by a corrupt driver, I did a SFC /scannow and found a violation that could not be repaired initially but I ended up being able to repair it after restarting. (Not sure why this is all mini)
