(a) Where do we download Windows 10 manuals from, please?

(b) Meanwhile the problem that drives me most potty - I use "restored down folders" for many purposes, eg copying files between: but now I can't move them and they sit on top of each other in the centre of the screen. How can I move a "restored down folder" to where I want it on the desktop, please?

I first downloaded Windows 10 three or four days after the start and as far as I know it's had all updates.

Thanks, colleagues - Eric (Birmingham UK)
