Hi Basj,
Thanks for your reply! Unfortunately I had already tried this option (and just tried it again) but this setting just disables the whole app list from showing on the start menu. Picture attached of what this setting change did.
Just to be clear; I still want all the programs shown on the start menu. I'm hoping to remove the top header that says "All apps" and ideally remove the alphabet header line items - but not too stressed about that as I can certainly live with those haha!
Thanks!
