See my earlier post - it's just about my waiting as all of you.
Subsequently having done everything others have mentioned - scan, store reset, etc., etc! I found this from another site after getting a corrupted file message from scannow.
Open Administration Command Prompt (rt click the start icon and select command prompt (Admin))
Type at the cursor
Dism /online /cleanup-Image /RestoreHealth
I'm a relative novice but I don't think the capitalization matters - perhaps others will tell.
It takes a while to go through. But it said finally it had fixed a store issue.
Then I found after a reboot I had 13 updates. And I'd already checked thoroughly earlier that there were no more updates needed. Can't explain that, sorry! So I'm now having a go at another download, probably number 10 or so.
If this was any other business offering such a service in any country in the world, it would (and should) be drummed out of business.
Now I'm waiting to see if my download attempt will get past 50% presently at about 45%!
SORRY - folks just checked - it's bombed out at the same point again.
As a novice again, I think a lot of this may be from the lengthy time of the downloads and ISP responses. I might just wait a few more days.
A pity there's not a disc purchase option, because relying on bytes across the ether must be prone to errors in data.
I'm sorry - but its back to the drawing board. The trouble with universal downloads is that you can't get a quiet time to download!
