Program Deactivator from AVG PC Tuneup is a great utility which detects which service is running in the background and also shows how much load it's putting on system and gives option to put it to sleep thereby speeding up your system. I've not come across any other software which does this. Most of them let you disable starup entries but there are background services still running.
Does anyone know of any alternative free software which can deactivate programs or any manual way to do it? I know using msconfig command it is possible but one does not know how much load which service is putting on system. Also, to use that program again one has to again go into msconfig and enable that service which can be time consuming.
