Ive been looking at a friends computer this afternoon who after installing CCleaner found that the after entering password it would take about 5 minutes for the computer to start up and display the desktop. Eventually I told the CCleaner program to run on start up and now it boots up fine. I was wondering if anyone knows why this would be the case as normally a program will slow a computer down if it runs on start up not the other way round.
