Tks Motorcycle Mama....Answers I needed. I've moved all the crap to a folder so clean my 'desktop' up. I then deleted the service books for the messenger apps, although I understand they will probably be pushed back.
I just read elsewhere that I can uninstall the pre loaded themes? Found instructions for using the Desktop software. Think I'm gonna try that. There were 6 or 7 themes preloaded :(
