I have checked with the windows help community with no luck only to find out that 24 others had the same issue.
The cumulative upgrade goes through all of the steps that every upgrade to windows 10 has had this past month until the final 1%. It will count up the progress to completion all the way to 99% then it shows the message "We couldn't complete the updates - Undoing Changes - Do not turn off you computer." After returning the computer to the original version it stops.
I'm on the slow ring an am running build 14393.187 and this update would have taken me to 14393.222.
My PC has failed to install this upgrade ten times now. And with the auto download I have no choice but to run the install every time I want to shut down the PC.
Has anyone hear of a fix for this issue?
