[SOLVED] Upgrade Win 8.1 to Win10 fails 0x800F0830 – 0x20003

This weekend I have to upgrade a small network to win10 ( around 10 computers).

After a few tries I realised 4/4 devices I tried failed with the above error.

So, I tried classic suggested solutions:

  1. sfc /scannow ( with dism commands where it was the case )
  2. deleted software distribution and cartoon folders
  3. doing all updates

…none of this helped in my case; but at some point I realised that browser is outdated and decided to install manually Edge and then used MediaCreation Tool to do an in-place upgrade

So far 2/2 computers worked.

Hope will save other hours of debugging, enjoy !

later edit: rest 2/2 were done without step 2, just installed edge and in-place upgrade worked
