I was unable to run services.msc., as it my system would hang at start up. So the above solutions didn't help me. Anybody with a better Tech background correct me if I am wrong with my understanding of svchost: svchost.exe loads/calls apps at start up. It seems that in accidently adding new windows components, something was not properly installed. everytime svchost called/tried to load the mis-installed process/app, the system would hang (at start up). I had to end the process in task manager, then went to add/remove windows components and took out the two or three items that I could remember failing to install properly. (They were additional network tools) Ta Da. what an R-PITA.
