Thanks Barry for your help there.
I will give those links a shot.
Many thanks again. And No I won't go near prefetch.
Mind you Prefech is a topic on its own.
Some people say Prefetch is great to clear the junk from your PC that gets collected from websites etc. And some People say don't ever go near Prefetch it messes up your PC.
So you are left to think. Who do I believe! But I choose not to use Prefetch.
