Seems like not only DTH but even Windows read my posts, last week I disgusted with Windows regarding their Free Windows 10 Upgrade after getting Marshmallow, since I was angry as whole world getting Windows 10 and I was getting update of Windows 8.1
2 days ago I got the Windows 10 icon in the tray when I click it asked me to upgrade I expand options and found option of reserving the copy when I click it just said "no needs to do anything its yours" keep it, this one is specially for you
Then decide to recharge 3G

update was of 2.8 GB

I received Windows 10 as update and not like ISO, its automatically update Lappy by its own and then finally W10 is here
