Thankyou for adding this. I certainly didn't know and i'm very grateful!

There was a thread that listed the page you use for storing your Microsoft serial no. Does anyone have that link?

it is asking for xbox one sr no. i didnt had any old version. only got the one S version. would i still get it? its not letting me proceed without xbox one serial

Thanks, just got mine yesterday and well pleased with it so far. Fantastic deals on the games at the moment...

You need to have owned a previous xbox one console and to have that consoles serial number

I did this a couple of months ago, you need to link both the serial numbers of your old xbox and the new one to your Microsoft account, wait until both show in your devices. I then contacted them through chat, they checked I had registed them and then got my details and sent it out. It doesn't come with retail packaging it comes in a throwaway foam plastic sleave. (incase you plan to sell)

If you are new to Xbox one and bought the current model, Microsoft will send you the cables for £29.99. You'd think it would be way cheaper to buy these cables from any other retailer but it quite the opposite

Thanks. Been meaning to do this for a couple of weeks but kept forgetting. Finally got it done and glad it's still free :D.
