Thank you for your speedy reply.
I'm not using the Winapp2 extension. I've reinstalled Ccleaner as you suggested and that did improve loading times, its now 20 seconds when not connected to internet.
As far as it needing to connect to the internet is concerned, I understand the reasons you give, what I don't understand is why it needs to happen before, or while the program is loading.
I will keep experimenting.
