Yes, 8.1 with bing qualifies for a free upgrade.
Hi Dom,
I bought a cheap box with 8.1/bing and have not had the upgrade registration option. I remember reading someone said it should get the Windows 10 Home option though.
We'll have to wait & see what happens. I'll not be upgrading mine as it's only got a 32gb SSD but I only use it as a ScreenConnect server
This is now visible on my Windows 8.1 with Bing machine. The following required updates were missing kb3035583 & kb2952664 and have only just appeared in Windows Update...
