Microsoft confirmed at the Windows 10 event on Wednesday that all devices currently running Windows Phone 8.1 would support the new operating system when it becomes available later this year.

And while this is indeed good news, because all Windows Phone 8.1 devices will be upgradable to Windows 10, it turns out that some low-end models might actually get a limited Windows 10 experience.

That's because certain features require more powerful hardware, Chris Weber, corporate vice president of Sales for the Microsoft Mobile Devices group, explained in a post, pointing out that, while all devices would support Windows 10, some might only miss a number of options.

Flagships likely to get the full Windows 10 treatment

While Weber didn't say a thing about the features that might not be available on low-end phones, it's believed that flagships, such as Lumia 930 and Lumia 1520, will get the full Windows 10 treatment when the OS becomes available.

“Windows 10 has been designed to run well on today’s Lumia phones. Like any upgrade to a new platform, not every phone will upgrade or support all possible Windows 10 features, and certain features and experiences will require more advanced future hardware,” Weber explained in his statement.

“Our goal is for the majority of the Lumia phones running Windows Phone 8 and 8.1 to join the Windows ecosystem along with an expected hundreds of millions of PCs, tablets and other devices running the next generation of Windows.”

Windows 10 for Phones preview coming in February

Microsoft will ship the very first preview version of Windows 10 for Phones in early February as part of a Phone Insider program that will also debut next month.

The company says that only those who want to deal with bugs and other performance issues should deploy this build because it's really prone to glitches.

But just like the Windows Insider program for PCs, the Phone Insider initiative is supposed to help Microsoft collect feedback for its platform and improve it in a way that would better tackle users' needs.
