Microsoft launches Windows 10

Microsoft launches Windows 10 today just as expected, making it available as a free upgrade via Windows Update and as a retail product to users in 190 countries. Unveiled back in September 2014, its goal is to bring together a wide range of devices, from tablets, smartphones, and computers to niche products such as Surface Hub or HoloLens. In the Windows Blog post about the new OS, Terry Myerson writes "Our vision was one platform, one store, and one experience that extends across the broadest range of devices from the smallest screens to the largest screens to no screens at all."

Considered by the Redmond giant to be "the best Windows ever," Windows 10 packs the following highlights:

• The old Start Menu is back, now complemented by Live Tiles
• Enhanced Windows Defender and Smart Screen for improved security
• Voice, Pen and Gesture input
• Designed to run Office and Skype
• Cortana personal digital assistant (only available in a few markets for now)
• Microsoft Edge replaces Internet Explorer
• Integrated Xbox App
• Built-in apps also include Photos, Maps, music app Groove, as well as Movies & TV
• Easy access to the new Windows Store for easy access to apps and media content

Just like OTA Android updates, the free Windows 10 upgrades roll out in phases, so not everyone will get the notification today. Windows Insiders running build 10240 already have the version Microsoft releases today, so all they have to do is check Windows Update to ensure they have all the final updates installed. On the other hand, the Windows Insider Program does not stop here, as Microsoft promises to reveal details about the next wave soon.
