Gentlemen, I salute you both sincerely with thanks. "Keep track of the Weather" that you suggested was exactly what was required. The original icon is for London, on clicking search, enabled me to icon my home town and now works exactly as previously. In the start screen I have two icons London and my own town name. As I have no wish to mess things up, as no doubt you realise that I am prone 100 per cent, is it safe to remove the London icon or leave well alone? It can be said with all sincerity, if in trouble Windows10forum members will help you out. Please accept my thanks appreciated.
As BigFeet said MSN Weather app was correct.
