Of course I tried. Was that "did you try" really necessary? You might as well have added "you idiot" to your question.
RA apparently did not understand my question. I wrote in my previous post the following:
**"**The reference to a cmd window makes no sense to me since I am seeing these error codes when I try to download and install -- not in a cmd window."
The error codes I was asked to copy for comment have never been in a cmd window. So I do not need to copy from the cmd black box.
As I have stated here before, I cannot download and install certain "critical" windows updates. Often, it gets stuck at 5% and will not download more than 5%. When I can occasionally get to the "install" point and follow the instructions to restart, I ALWAYS get the message that they could not be installed and that the computer is undoing changes. The error codes change all the time and none of the windows help screens have anything to offer.
The error codes are not in a cmd box; they are in a window about updates and the details of why they would not install. There is no easy or intuitive way to copy that screen -- right clicking on a screen does nothing; there is no pull-down list of options, no "edit" or "mark" visible. Highlighting and using Cntrl C does nothing.
I have run the windows update troubleshooter many times and it ALWAYS says it fixed something -- but I still cannot install updates.
Why is this so difficult and why do people trying to answer here seem so intent on cryptic (and subtly critical) partial clues, instead of straight-forward answers? This is not a law school class for first year students where the professor needs to ask questions that he or she thinks will lead students to learn to think for themselves -- so the attempt at Socratic method is both inappropriate and unhelpful. It is no wonder Apple has some many devoted fans. They don't hide the ball like some in the "Microsoft community" seems to delight in doing. This is a quick trip to loss of market share.
