Windows 10 Pro Upgrade to Version 14393 "Anniversary Edition" - Microsoft Community

 hello,

 my problem have just installed windows 10 pro upgrade windows 8.1 pro [installation the official dvd iso] , went > resulting in windows 10 pro version 10240.

but... after 2 hours of testing , checking new features, decided proceed "anniversary upgrade" version 14393 available microsoft [windows10upgrade28084.exe].

all went well, until process reached 85% of updating.

then installer displayed message "something went wrong" error code: 0x80070057.

i tried apply update again, , again - same thing happened 4 times in row > error @ 85%.

i checked windows registry errors , corrected issues, i performed disk cleaning , restarted pc same thing happened again.

considering whole process start until error appears takes 1 hour, trying upgrade 4 times no result total waste of time.

i want to mention 1 day before did same upgrade version 14393 on laptop of friend, , went without any problems.

this problem appeared on desktop pc, powerful enough support windows 10 latest version.

if can find solution grateful.

hi calin,

to address concern, suggest run dism or system update readiness tool. windows updates , service packs may fail install if there corruption errors. example, update might not install if system file damaged. run tool, please refer link.
