buel.Most of those on the right hand side start with the computer.Any of them not needed to run at start up go to Run and Type in . msconfig.start up.And untick any that should not run at start up.Apply Ok.Reboot a box will appear just tick the little square ok and it will not show again.Make sure you do not remove your security programs.That should stop them from showing.
If it means you have to download Windows Defender probably better with msconfig.But I agree with you msconfig is not for the learner,but you can always go back and retick anything that may be needed. I only say that as I have never liked Defender and would not recommend anyone to use it.Like Norton it has a bad image.About 50% of folk like it and 50% dont.A bad average.But you are right I never thought about there inexperiance in removing anything and they may be better waiting for one of there family or friends to help. Not sure if you use Winaso but that is great for removing start up programs. I am sure there are others but that is the one that I use sometimes.
I agree with Sea Urchin. Any alterations made in ccleaner are reflected in msconfig and it`s much easier to see the details of each program. You should google any program you don`t recognise and you`ll generally find out whether the program is required to run at start up. (Look in the file details column, not the Program column and google the filename at the end of the path.)
