CCleaner auto-cleaning on boot ! Not asked for!

CCleaner for Windows
1

First the details: 

Windows 7 Ultimate SP1.  CCleaner Professional 5.55.7108 64-bit

I've just realised that CCleaner has started to AUTOMATICALLY CLEAN upon startup reboot after I had a blue-screen. 

I did not realise this was a "feature" of auto-starting CCleaner, especially when, as far as I can tell, I've set the options to ALWAYS PROMPT before doing anything.




This is very annoying, because it prevents analysing what the heck happened just before a blue screen.




Is there any way to turn this auto-clean off but still have CCleaner start with Windows (to give me a tray-icon and do its monitoring)?

Uncheck run at startup, this is a badly worded setting, it means clean at startup
