I would have expected to be excluded from that returns policy, due to software licencing... ...I could, for eg, activate the Office subscription, then send back otherwise, effectively getting a free year of Office/1Tb OneDrive.
Out of the two, one had the 360 in win8 and the other didn't, I found it by seeing Acer Apps were installed that I might need before doing an image BU and upgrading to win10, there was noting on the box or paperwork about the Office offer.
I created a Admin account on first time Start Up (win8) rather than signing in using a MS Account, just in case I needed anything to keep before win10, and when clicking on Office it come up with create your Acer ID account, blah, blah, and after a bit of faffing around it gave me the option of 360 and OneDrive for a year,
as said the other Tablet didn't have it, so supposedly was wiped off when being refurbished
.
Was toying with the idea of putting the other one back to win8 and loading the Acer stuff on it to see if it will give me the option again using a different Acer ID, but tbh now Ive put a clean Win10 on it already, not sure if I can be arsed to do it all over again,
we'll see.
