The Windows Blog has just announced that - “a free upgrade for Windows 10 will be made available to customers running Windows 7, Windows 8.1, and Windows Phone 8.1 who upgrade in the first year after launch”
The upgrade is permanent. You have a year from release to get it.
Other notable news -
- Word, Excel, and PowerPoint will be included with Windows 10 on tablets and phones.
- Cortana to PC was also just confirmed
- Microsoft HoloLens – Scott Hanselman explains it best at Rollup: Microsoft HoloLens, Surface Hub, Windows 10, Xbox One game streaming and more.
“Wow, an augmented virtual reality headset from Microsoft? Is this Oculus? Or Google Glass? It's something else. It's clear so you see the projected images as if they are in front of you. It's not a tiny screen like Glass or a screen that blinds/immerses you like Oculus”
With these amazing changes, I agree with Scott’s assessment that Microsoft is working toward’s Satya’s vision -
"We want to move from people needing Windows, to choosing Windows and loving Windows. That is our bold goal with Windows." - Satya Nadella
