Run these in sequence from a Elevated Command Prompt:

Dism /Online /Cleanup-Image /StartComponentCleanup
Dism /Online /Cleanup-Image /RestoreHealth
SFC /scannow

If anyone fails, run it and the one after it again.

Thanks will try when i get home later , will let you know.

The Media Creation tool checks the integrity of the download after it has been downloaded.
It's very strange that it should be corrupted.
Where are you saving the download to?

First one completed successfully , second command said needs to find directory where files are located to replace corrupt files so that one gave an error .

sfc/scannow gave a corrupt files message again as expected from the failure of the second command.

...second command said needs to find directory where files are located...

These may be on the CD or the USB stick that you installed Windows from.
If the disc isn't in the CD player or the USB isn't plugged in then the recovery files won't be found.

(At least, I think so!)

SFC reported errors about files and referenced CHKDSK?
Is that right?

After following Ztruker's suggestion,

Launch and elevated Command Prompt and run a Read-only Disk Check

chkdsk C:
*** do not add any parameters

then run Disk Check again with the fix parameter

chkdsk C: /f
*** this should prompt you to schedule the check on the next boot, answer yes

Restart your machine - Disk Check will run before Windows loads

Try SFC again.

Tried this one multiple times, including the "f" but (minus the capital C after command ) and the corrupted files seem to never get fixed , i keep getting the same " chkdsk was unable to fix some of them" message.

Very good point , i did copy the creation tool download on to a blank DVD but have not used it , i will post a screenshot of whats on it.


I am just confused about the correct command . I installed Windows without a DVD or USB stick , just followed the upgrade from MS so far.

I will try the second command again with DVD installed , hoping it works.

Just tried and this is what i got.
