After months of rumors and speculation Windows 10 for phones has been officially unveiled by Microsoft. Forget Windows Phone 9, in fact forget Windows Phone altogether, because this is just Windows...on a phone.
Update: The first publicly available build of the next Windows operating system for phones has been released to Windows Insider program members.
This first build is simply a technical preview of Windows 10 for phones, and as such contains just a sampling of the features we're expecting to eventually see.
As an unfinished build, this Windows 10 for phones technical preview is liable to be unstable, and Microsoft recommends caution when installing it - maybe on a secondary Windows Phone device rather than your main phone.
To get started, download the Windows Insider app from Microsoft's digital storefront. Oh, and only users with the Lumia 630,Lumia 635, Lumia 636, Lumia 638, Lumia 730 or Lumia 830 will be able to install it for now.
We're expecting to learn even more about Windows 10 for phones in early March, but there's a whole lot more to dive in to until then, so settle down and tuck in to all the tasty details about Microsoft's upcoming mobile (and desktop) operating system.
Cut to the chase
- What is it? The next major upgrade for Windows Phone
- When is it out? Later in 2015
- What will it cost? Nothing, it's a free download
Windows 10 for phones release date
Windows 10 will ship for desktops later in 2015 and there's every chance that the phone version will arrive at around the same time. Unfortunately Microsoft isn't getting any more specific than that at the moment. More information is likely to come from Microsoft's March 2 press event at MWC 2015.
However a preview build of Windows 10 for phones is expected to land in February, probably after the first weekend of the month, though this will be an unfinished version aimed more at developers than end users.
The good news is that when it does fully launch it will be available for a year as a free upgrade to existing Windows devices, including those running Windows Phone 8.1. So if you have a Windows Phone 8.1 handset you should be able to get Windows 10 on it before the year is out.
One OS to rule them all
The key thing to know about Windows 10 for phones is that while the version running on your handset will be optimised for a smaller screen it's still just considered Windows 10.
So apps and features will look similar on your phone to on your desktop. You get the full versions of Office, Word and PowerPoint and they will look and operate much the same as the desktop versions.
Settings screens will also look and operate in the same manner across devices and apps will be universal, so Photos, Music, Videos and more will be much the same on desktop, phone and tablet and you can switch between Windows devices almost seamlessly.
It's all about unity
Speaking of seamless switching, Windows 10 is designed to be unified between devices, not just with a similar look and universal apps, but by having phone and desktop work together.
So for example if you clear a notification from the Action Centre on your Windows 10 phone, it will also disappear on your computer and vice-versa.
You'll also be able to open and edit Microsoft Office documents on all your different devices, as files will be synced in the cloud and a recent docs list will give you quick access.
You'll still get live tiles with Windows 10 for phones and it doesn't look identical to the desktop version, but it's not far off. A background image will bleed through the translucent tiles, allowing you to personalise the Start screen beyond just changing the colours.
Swipe to the right and you'll get an apps list as before, but now recently installed apps will be shown at the top, so you can more easily find whatever you last downloaded.
There's also a new layout to the settings screen, making it look a lot more like the version found on desktop and tablets. In fact a few leaked screenshots of the Windows 10 for phones technical preview have emerged, so you can see the settings screen for yourself above, along with Action Center (or whatever it ends up being called this time round).
As you can see there is a wider range of quick settings than on Windows Phone 8 and a different colour scheme, with blue icons.
Keyboard and messaging
The keyboard is getting a bit of a touch-up on Windows 10 for phones. It's still the Word Flow keyboard from Windows Phone 8.1, but now it can be resized and even moved around the screen, so you can position it perfectly for your device and fingers.
Plus you can look forward to in-line messaging, allowing you to switch between SMS and Skype without switching apps and it's rocking some fancy dictation skills, as it can output symbols rather than writing the word and will even head into your contacts list to check how you spell a person's name when you speak it.
Camera and photos
The new photos app will be one of many universal apps and being universal it also syncs your images across all your Windows 10 devices using OneDrive.
Not only that, it also removes duplicate images, automatically creates albums and automatically enhances your photos by removing red eye and the like.
If you're not using a Lumia phone then you'll also see some big changes to the camera app, as Lumia Camera is becoming the default app on all Windows 10 handsets. It brings with it auto-HDR, 4K video recording, Rich Capture (which can combine images to create one superior photo) and Dynamic Flash, which takes a photo both with and without flash and then lets you adjust the flash level after the fact.
If you're already using a Lumia then you won't have to wait for Windows 10 for phones to make use of these features, but the new version of Lumia Camera will also be faster both to launch and take photos than the current version.
Big things are happening to Internet Explorer as part of Windows 10, in fact it's not even clear whether the new version will be called Internet Explorer, as it's currently codenamed Project Spartan.
The biggest addition is that on desktop at least you can now mark up web pages with notes and drawings and then share them with other users, though we're not sure whether this feature will be available on the smartphone version or not.
More to come
That's all we know so far but with a preview build of Windows 10 for phones launching in February we're bound to find out more soon. In the meantime head on through to the next page to read up on all the rumors we heard in the run up to the announcement.
