UNBELIEVEABLE MICROSOFT ISSUE

I have now spoken to or emailed 5 Microsoft techs - WITH NO SOLUTION!!! And it's their software 'upgrade' which has caused all of this. Can you imagine the waste in a company which repeatedly gives advice that doesn't work - 'Do this - this will happen...' I do, it doesn't. The buck has been passed and passed and passed and passed and passed and passed. Literally. Now I am told to wait for a call from the "research team" member who will help me. What a joke.
