Right, now I am stumped???
I burned the English International installer to DVD and tried that installer and it also failed at 33%
All quite odd, so revert to plan B and forget about W10 for now and just cope with the WU idiocyncrasies I experience with W7 ~ heh ho!
Edit ~ I wanted to check the "countdown clock" on the W10 upgrade again here
https://www.microsoft.com/en-gb/windows/windows-10-upgrade to try one last time using the Media Creation Tool and found there was a new tool obtained by the 'Upgrade' button
Bearing in mind I last grabbed the media creation tool on the 27th July this surprised me and nowhere have I read that the tool had changed??? It was called Windows10upgrade9194 . exe from the 'Upgrade for free' button.
I downloaded and ran it and does a compatibility check which my PC passed the 3 stated critera CPU, Disk Space and for the life of me I cannot recall what the third said!
It is currently at 30% download far quicker than the ISO download
But bearing in mind the "countdown clock" says 37mins and falling to upgrade for free I can only surmise that this is the time to get the 'Upgrade for free' tool not a deadline to use the download especially as the GUI said something like you upgrade at any you like.
PS Edit ~ whilst I was typing this post the "Windows Upgrade Assistant" disappeared.............oh b***er I thought not another MS failure. Well thinking I would rerun it I get a message that it 'already running' so something going on in the background perhaps positively
It would be nice if the GUI window stayed open to keep you informed!
Oddly (there's a surprise) there is nothing in Task Manager to show that it is running and indeed anything other than the browser running???
Though router internet light flashing like a good un and all four i5 cores busy.
