For those that missed it, Microsoft has a blog update showing what was shown at today’s event for Windows 10. A lot of really cool stuff. Windows 10 Insiders get an update within the next week to showcase a lot of the new features. Should be extremely fun to play around with.

Some other excellent things were shown during the presentation: HoloLens, Surface Hub, Windows 10 Phone, Xbox Streaming… A good presentation, for sure. I’m definitely impressed with the new Windows 10, and I knew a bit of this before hand. Seeing it in action made a big impression, as did some of the other technologies shown.

One big question answered – if you own Windows 7 or 8, you get a free upgrade to Windows 10 as long as you do it within a year of release. No, this isn’t a year free of a subscription service. This is a year long promotion to get it for free – for the life of the device.

Today was a monumental day for us on the Windows team because we shared our desire to redefine the relationship we have with you – our customers. We 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.*

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 additional charge. With Windows 10, the experience will evolve and get even better over time. We’ll deliver new features when they’re ready, not waiting for the next major release. 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.
