Microsoft outlined their plans to make Windows 10 a valuable platform for developers. The big hurdle to cross is getting the system into the hands of users.
As was previously announced, Windows 10 will be a free upgrade for the first year to those running Windows 7, Windows 8, and Windows 8.1. Microsoft is also aiming to get Windows 10 onto 1 billion devices within the first two to three years of release. This will be helped by the fact that Windows 10 will run on PCs, tablets, phones, and more.
