If disabling is what you want to do to the svchost, then go into services.msc and view properties and diable it or set it to manual. But before doing so, you NEED this service. When clicking on the svchost properties, click on the dependencies tab and see what all that service depends on or needs to have to run. I dont think your problem lies with the svchost personally as I always have 4 running, 2 systems, 1 network and 1 local. I am not running ICS or ICF, no proxies or DHCP.
