Microsoft surprised many in the tech world by naming their upgrade price for Windows 10: Free. Many had noticed that the upgrade price was 'Free, in the first year of Windows 10 being available' and wondered if that meant that it would mean that any updates after that time would be paid updates.

Terry Myerson. head of Microsoft's Operating Systems Group, moved to quell any concerns and assure consumers that the 'Free' Upgrade might lead to a sneaky charge later down the road. "This is more than a one-time upgrade: once a Windows device is upgraded to Windows 10, we will continue to keep it current for the supported lifetime of the device – at no cost."

Myerson continued to compare this new vision of Windows to other Internet Services, such as Outlook.com or OneDrive. "The idea of asking 'What version are you on?' will cease to make sense ... We think of Windows as a Service – in fact, one could reasonably think of Windows in the next couple of years as one of the largest Internet services on the planet"

So, if you upgrade within year one, it will be free for the lifetime of that device, including updates and new features.
