Windows 10

Does anyone knows when Windows 10 is coming for all Windows phones in all countries?

Have you had a look at this?

Yes. But I am not using windows phone anymore. In past I was using once. Right now using Android. But yes in future I may go for windows by chance. Yes now all mobiles will come with latest os windows 10.

Have you had a look at this?

No, but thank you, I just did. There is no upgrade to Windows 10 for Lumia 625. :/ At least not for now.
