Microsoft has released the latest preview version of Windows 10 for smartphones, significantly increasing the number of compatible devices in the process.
The latest Technical Preview for those currently running Windows Phone 8.1 is now available on 35 Lumia handsets, up from the six devices able to run the first release.
It’s not just a compatibility boost either. Far from it. The new Windows 10 preview for phones includes Microsoft’s IE-supplanting Spartan browser.
There’s also the addition of six essential apps for Windows Phone fans to test drive. The new version includes Mail, Messages, Calendar, Maps, People and Phone.
The release comes at the end of a busy week for Microsoft’s Windows 10 team. On Wednesday the firm rolled Movies and TV shows into the new unified Windows 10 store, which will eventually be available across all devices.
The company is gearing up for a full summer release for Windows 10, which will be a free upgrade for the first year.
The full list of compatible devices for today’s roll-out is as follows: Lumia 1020, Lumia 1320, Lumia 1520, Lumia 520, Lumia 525, Lumia 526, Lumia 530, Lumia 530 Dual Sim, Lumia 535, Lumia 620, Lumia 625, Lumia 630, Lumia 630 Dual Sim, Lumia 635, Lumia 636, Lumia 638, Lumia 720, Lumia 730, Lumia 730 Dual SIM, Lumia 735, Lumia 810, Lumia 820, Lumia 822, Lumia 830, Lumia 920, Lumia 925, Lumia 928, Lumia ICON, Microsoft Lumia 430, Microsoft Lumia 435, Microsoft Lumia 435 Dual SIM, Microsoft Lumia 435 Dual SIM DTV, Microsoft Lumia 532, Microsoft Lumia 532 Dual SIM, Microsoft Lumia 640 Dual SIM, and Microsoft Lumia 535 Dual SIM.
Owners of those devices will have to sign up for the Windows Insider Program in order to access the software. Here's our guide to installing it on your handset.
Microsoft says more smartphones will become compatible in future versions, including those handsets outside of the Lumia stable.
"This is definitely not the final list of devices," wrote Microsoft's Gabe Aul, "and we’re still hard at work to let people with other phones get hands-on with Windows 10 in the near future, including non-Lumia devices as well."
