I tried all through the holiday break but I could not upgrade my old Win 7 laptop to Win 10 so I could take advantage of the $0.10 deals.
I had the same issue. Took my old Dell E1505 almost 24 hours idling on the Windows Update screen to initiate the W10 upgrade. Finally finished the upgrade and grabbed almost all the games I wanted. Unfortunately I missed the timed Halo Spartan game sale.
