Please encourage my laziness of not having to scroll through all the previous discussions and can someone please tell me simple terms answers to the following?
Will I lose all my pictures/documents etc? What prog/applications/features will I gain and what will I lose I'm on Windows 7? What is the best/worst features of Windows 10? How long on average to download it

? Has anyone upgraded to 10 and wished they hadn't. Finally is it reversible?
