Microsoft has announced that Windows 10 Technical Preview will be available to sample on more mobile devices from next month, Digital Spy reports.
The computing giant is opening the tester build of the operating system up to almost every Lumia handset on the market.
However, there are a number of glaring omissions on the list of supported devices, including the Nokia Lumia 930 and the Windows Phone-powered HTC One M8.
Windows 10 Technical Preview is a test version of the operating system that Microsoft does not recommend installing on your primary device.
The next build of the software is expected to be released in the coming weeks, with the consumer version of Windows 10 due this summer.
A full list of mobile devices eligible for Windows 10 Technical Preview can be found on the official Windows Blog.
