I don't see a reply from you to me in the place where I posted my problem with installing Windows Update KB4566782. However, I have gone back and read your suggestion to Robert Mumps and noticed that the error code you posted is not the one Robert Mumps and I have. Our error code is 0x80073712.
With all that said I have tried very few of the many suggestions I have gotten as some I don't feel capable of trying without making a mistake, and I don't want to mess up my computer. As I informed Robert Mumps I am going to get some advice from a relative, who is very computer knowledgeable, this weekend.
I am 84 years old and don't feel as comfortable coping with these kind of problems as I once did.
Also if you read my most last post to Robert Mumps you will see what I most recently have done.
