I followed the advice from posts on Apple and the last one on Microsoft where the advice was to delete all apple, iTunes, Bonjour etc files and folders.
I have (using the Microsoft Program install and uninstall program) removed everything relating to iTunes. So I uninstalled iTunes and attempted to reinstall, I have had a variey of error messages and I have searched them all, some of the suggestions were too scary for me to attempt.
My Windows PC updated today and I have been unable to open iTunes since.
