Let's go back in time
To provide a good answer to this question, we first dive into history. Because how did it all begin?
The very first mobile phone was the size of a brick and therefore not very comfortable to hold. It was an expensive device from manufacturer Motorola that also hung endlessly on the charger. If you watch a movie released around 1983, there's a good chance you'll see one passing by.
A device that most of us can still remember well is the Nokia 3310. This mobile phone was very popular around the turn of the century due to its compact size and built-in games.
A device that most of us can still remember well is the Nokia 3310. This mobile phone was very popular around the turn of the century due to its compact size and built-in games. And there was the BlackBerry: primarily aimed at businesses, with email and calendar as decisive features. The first BlackBerry (the 850) appeared in 1999 – not yet a smartphone as we know it today, but the beginning of "always being reachable" work.
The BlackBerry made email and calendar mobile and became a business killer feature, long before the app economy.
In 2007, the first generation iPhone hit the market and changed the market forever. Touch became the norm, apps became the ecosystem, and "phone" suddenly became a complete platform. Microsoft already had mobile ambitions (Windows Mobile on PDAs), but it wasn't until the early 2010s that there was a real restart for consumers: Windows Phone (later followed by Windows 10 Mobile). In February 2011, Nokia and Microsoft announced their partnership; in October 2011, the first Lumias on Windows Phone (Lumia 800/710) followed.
The key moments in a row, so you can easily place the rest of the story:
- 1999: BlackBerry appears (business: email/calendar as killer feature)
- 2007: iPhone puts touch + ecosystem on the map
- 2010: Windows Phone appears as Microsoft's "restart" in mobile
- February 2011: Nokia and Microsoft announce their strategic partnership
- October 2011: Nokia presents the first Lumias on Windows Phone (Lumia 800/710)
- 2017: Microsoft indicates that new features/hardware are no longer a focus
- December 10, 2019: Windows 10 Mobile end-of-support
- October 21, 2024: Surface Duo 2 support ends
- February 2025: Store/apps on Windows 10 Mobile work increasingly less (according to user/tech site reports)
With that timeline in mind, it also becomes clear why Windows Phone often revolves around one word: ecosystem.
A Nokia device with a Windows Phone tile interface showed a recognizable design but had too little app ecosystem to break through permanently.
Operating systems: why Windows Phone struggled to gain momentum
We now know that the start of the Windows smartphone took a long time to arrive. There were many plans and intentions that had to be adjusted and postponed repeatedly. And that has essentially remained the case. A form of indecision, it seems, that caused the operating systems of Apple (iOS) and Android to be much easier to use and also developed much better and faster.
That sounds like a management summary, but you could see it primarily on the streets: iOS and Android surged ahead in pace, models, and especially apps. Windows Phone had its own identity (that tile interface was appreciated by many users), but the platform continued to struggle with the app gap. And therein lies the pitfall: without apps, users drop off – and without users, developers drop off.
Introduced, but quickly falling behind
The first iPhone had a touchscreen that was immediately embraced by users. The keyboard of the BlackBerry suddenly seemed outdated, even though there are still users today who can't live without it. BlackBerry remained relevant as a brand for a while but eventually shifted towards Android. A symbolic turning point was the BlackBerry Priv: the first BlackBerry device that ran on Android by default (2015).
iOS and Android are now the most well-known and widely used operating systems, and app developers have massively joined in.
iOS and Android offered increasingly well-functioning apps – and that is decisive for most people. More and more models came onto the market. If you were comparing devices, sim only or mobile subscriptions, you rarely ended up with a Windows Smartphone. You also heard less and less about it. Microsoft was always lagging behind in the smartphone world, no matter how interesting the idea on paper sometimes was.
Why Windows Phone ultimately didn't make it:
- App gap: without apps, no users; without users, no apps
- Momentum: iOS/Android were in a speed that Microsoft couldn't catch up to
- Hardware choice: fewer models in fewer price ranges = less reach
- Developer focus: everyone builds where the mass is
- Microsoft strategy: services on iOS/Android became more important than having its own OS
That sounds harsh, but that's how platform markets work: without apps, users drop off, and without users, developers drop off. Microsoft ultimately also explicitly chose to build its services on iOS and Android instead of a proprietary mobile OS.
2017–2019: from "no longer a focus" to the official endpoint
In 2017, Windows CEO Joe Belfiore indicated that new features and new hardware for Windows 10 Mobile were no longer the focus. Microsoft preferred to continue building its services on iOS and Android. This became particularly clear at the time through Belfiore's reactions on X/Twitter (and the reporting about it), not through a major press moment.
The definitive closure came on December 10, 2019: Windows 10 Mobile reached end-of-support. From that moment on, there were no more security updates and official support.
On paper, you could still use the platform for a while, but in practice, it means: without updates and without a living ecosystem, it becomes a dying matter.
2026: the Microsoft Store no longer works for many Windows 10 Mobile users (well)
And that "dying" became painfully visible as early as 2025. In February 2025, multiple sources reported that the Microsoft Store on Windows 10 Mobile no longer functions well. In other words: even if you still have a device that starts up fine, installing or updating apps suddenly becomes a problem.
From the Windows smartphone to the Microsoft Surface Duo (Android)
Microsoft's strategy has changed. Instead of Windows on your phone, later – at the beginning of 2021 – a striking alternative emerged: the Surface Duo, a device with two screens running on Android. This shifted the focus to hardware on Android, with access to the app ecosystem that most users rely on. It seems that Microsoft ultimately also recognized that app choice is the decisive factor for many users.
This device was positioned as an alternative to phones with a foldable screen, but in practice, it mainly works as dual-screen: two separate screens next to each other. Between the screens is a bezel, causing the image not to flow smoothly but to be interrupted. However, this is not necessarily a problem for this concept: it feels more like "two screens in your hand" than one large flexible panel.
The start of this line was mixed: the idea was distinctive, but there was also criticism regarding price, cameras, and teething problems. Later, a second version (Surface Duo 2) appeared, featuring better cameras and 5G. However, this chapter has also now been closed.
Surface Duo: interesting attempt, but also ended
Microsoft's own support pages now list both Surface Duo and Surface Duo 2 as "end-of-servicing": no newer Android versions and no more security updates.
Additionally, it is widely reported that all support for Duo 2 ended on October 21, 2024.
What does that mean for Windows Phones now?
In short: Windows smartphones are not "sleeping", but really gone. Microsoft has been focusing on its apps and services on iOS and Android for years, instead of on its own mobile OS. And if you still have a Windows phone lying in a drawer – or are even still using it – it's good to realize that it's not just about "no updates". Also, surrounding components are falling away: the Store that no longer cooperates, apps that can no longer be installed, and services that are slowly stopping support.
Do you still have a Windows phone? This is wise
If you still use one (or have one lying in the drawer)? Then it's good to keep this in mind:
- Don't count on security updates or a reliable ecosystem anymore
- Preferably don't use it for banking, 2FA, or password apps
- Transfer photos/contacts/calendar to a modern device (iOS/Android) while synchronization still works.
- See the device as legacy: fine as nostalgia/backup, but not as a "safe daily device".
- Business: phase out instead of "just rolling on", especially because apps and Store functionality may fall away.
For sensitive matters like banking, two-step verification, or password apps, you want to be able to rely on current security updates and a functioning app ecosystem. That is exactly what Windows 10 Mobile can no longer provide since end-of-support, especially now that the Store is faltering in 2026.
