when we choose don't start with windows, it should just do that without having to find all the options that would prevent it to NOT start with windows.
Don't put the option if you don't register it and ignore us.
I believe that you mean "Run CCleaner when the computer starts"?
And I believe that you have misunderstood just what that does.
Ticking "Run CCleaner when the computer starts" simply means that when you start your computer CCleaner will do a clean in the background (so you don't see it onscreen) and then close so that it is no longer running.
It usually takes seconds to do that.
The thing that starts CCleaner when the computer starts, and doesn't then close it, is "Smart Cleaning".
Smart Cleaning monitiors your computer for a 'build-up' of junkfiles and removes them when they reach a certain level.
If you want to use Smart Cleaning then CCleaner has to be running all the time, otherwise it can't monitor what is building up.
I hope that clears up the misunderstanding.
