A disaster so far. Installation worked OK Desktop shows (rearranged but still all icons there) There is no Start button at bottom left, and anyway Icons at bottom of screen (taskbar and system tray) don’t work - when the curser moves to them, instead of an arrow it become an “I” and does not open shortcut. Desktop shortcuts for web addresses don't work, but those for things on the PC (like Word) do work. How do you get to the Control Centre - I cannot open programs ? .
