I have had a real stinker of a week with my PC being very slow. After trying many things, I had a look at which processes were in use. CPU usage was at 100% with Isass.exe taking 60% up and svchost.exe taking 40% up. I tried cancelling the Issac and couldn't but the system allowed me to cancel the svchost and low and behold the computer ran like a dream and does all the time now as long as I repeat this process. My question is what is svchost.exe and how can I stop it from starting without ctr/alt deleting?
i am now confused re the link because first paragraph says it is essential to system, second one says delete it. i have 5 instances of svchost.exe running on my machine 3 say system (one of which is running at 24 meg) 1 says network service and 1 says local service. which should i have or not have.?
