This can maybe be usefull...
It is the link to windows 10 with the possibility to download it on an usb device.
Upgrade when you want, the free upgrade will be over in some months.
If you already have windows running you dont have to buy a new key.
I am personnaly not a big fan of this windows but soon or late I think we all have to make the switch when our actual os (win7, win8) wont be supported.
