At what point does it fail? It would help if you filled out your system specs as well.
Windows 8.1
ASUS eK COMPUTER INC.
ASUS All in one PC Series
Intel ore i7-4500u CPU @ 1.80GHz
8GB RAM
64 bit
NVIDIA GeForce GT 740M
What other specs do you need?
The PC is only a few months old.
I just kept getting the message each morning saying the Win 10 upgrade had failed. I have two other PCs and they had no problem with the upgrade, they just upgraded automatically.
I have always installed all the Windows updates apart from Silverlight and a Canon printer driver that could never be installed.
I did download the Win 10 ISO a couple of months ago but not being very computer literate I'm a bit doubtful that I would be able to use this successfully, especially as there seems to be a problem with this PC upgrading.
