Thanks for the warning about Edge, Tim, and possibly also the Store. One of the things that annoy me about 10 is that it seldom lets me set any app that isn't from Microsoft (which most of mine aren't) as the default programme. I was hoping that if I got rid of the Store it couldn't try to make me choose an app from it!
I've already got rid of the tiles and I don't use that page as my home page anyway, I've created another one with links to all my preferred programmes on it, just as I had in Windows 7.
However I still want to delete them from the Start menu and there is no option offered for that. If I know the registry keys I can delete those and the pesky things will disappear completely! I've disabled One-Drive but it's still there and I'd like to get rid of that altogether too.
