Guys I have the same problem but I did it myself. So my svchost-netsvcs was getting a lot of cpu usage and when i was running games the sound (which is in the sme key) bugged(excuse my eng) and so i went to the key but didn,t knew what was the service that was getting so much cpu. I started to remove the services one by one to see which was that. Of course I saved the removed servc somwhere else. But one time i removed some services which wrere started whit I and a didnt saved them becuse the computer restarted itself. I didnt care because i thouthg thy wrerent important. I foun the svc i needed and everithing was fine untill I get the same problem as you. I know that it is one of the services i didnt saved but i cant find whats the name of it I tried ics,icsvsc,issvc but it is not working, so if someone of you who is whit working wih firewall coud go to start>run>regedit>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost>netsvcs open it and please tell me the names of the servc whit I.
