Win10 upgrade icon was missing. Found GWX.exe and ran to enable icon for upgrade.
Attempted upgrade from 8.1 PRO to 10. D/L OK and showed preparing to install. Then as the install started it immediately failed with error 800070005. Tried several times on both mine and wife’s identical PC’s with same result.
Interestingly, had previously upgraded older Win 7 PC, Win 8.1 HP laptop and an old Hp laptop that originally ran Vista and was upgraded to Win 7 then to Win 10 Home with no problem at all.
Research indicated it is a permission problem. Normal Windows updates install with no problem on both machines. Suggestions were to get the Media Creation Tool and use it to do an in-place upgrade OR go to Tweaking.com and run their repair tool and then attempt the upgrade from the GWX icon.
Both machines are set up with SSD’s as boot drives and all data is on a second HDD with File History running.
Any thoughts on this as to which way suggested previously to go or any other method to solve this?
TIA,
Jim
