    I upgraded briefly about 2 years ago from 7 to 10 and then within an hour went back to win 7. Since that time my "setup backup " and thus backup would not complete.. a couple of days ago after some digging i was getting error code ox80041321 for which after trying a couple of micro soft fixes to no avail I was able to utilize an external hard drive and with "windows easy transfer " save settings pics and users and guest info .


    Having done so thought would try the upgrade again although it is expired it apparently still works for those with an active and licenced win 7 computer .


    I also thought doing so would correct the corrupt files in the task scheduler and thus once windows 10 was installed this would either correct or have entirely new files so this would be resolved. . The update was done a few minutes ago however on the final final stages i got a screen that said it did not complete and it stated " 0x1900101-0x20017 " it also stated " installation failed in the safe -os phase with an error during boot operation . In addition within this box it suggested i go toHTTPS://go.microsoft.com/pwlink/?linkid=528892



    sorry for the length of this however i don't know if this site is a scam or truly Microsoft so i did not go there .


    Thanks in advance for any assistance or direction to go this this .

    Maybe it holds the clue.


    Did you try the list of quick fixes which include removal of third party AV.
