Supported models, new features, rolling back, hands-on

Microsoft has released today the first Windows 10 version to some smartphones. Keep in mind that this is an early build so it could be buggy and you may encounter glitches.

While the old Preview for Developer gives you access to finished official builds directly from Microsoft, Windows Insider provides unfinished versions under development, just like Windows 10 for PCs. Fortunately, Microsoft has promised a special software tool for rolling back to Windows Phone 8.1 if something goes wrong (we will post an article shortly after details emerge).

Only a subset of all smartphones (which has a recovery image available) can install the first Technical Preview of Windows 10, but Microsoft will include more devices in the next releases. Here is the list with first supported models:

• Lumia 630
• Lumia 635
• Lumia 636
• Lumia 638
• Lumia 730
• Lumia 830

Microsoft explains why high-end models like Lumia 930 and 1520 are not supported. A new feature called ‘Partition stitching’ is still under development but will be coming soon. It will allow Microsoft to adjust the partition dynamically during the installation process for smartphones with storage more than 16 Gigs so more device will be included in the preview once ‘Partition Sticking’ feature is completed.

To install Windows 10 on your eligible smartphone you need to be registered as a Windows Insider and then install the special Windows Insider app on your phone. There are two other requirements for getting Windows 10 – Windows Phone 8.1 and at least 8 GB of storage.

After logging-in to the app you will see the current builds available for your device to download.

The first build of Windows 10 for phones introduces full size background, the first universal apps (Photos), Expandable Action Center, Improved speech-to-text, and Interactive notifications.

A lot more features and supported smartphones will be coming in future builds – more universal apps (Maps, Calendar, Music, Outlook), Touch optimized Office, and other improvements.
