Microsoft Details Why Windows 10 Technical Preview Was Not Released For High-end Devices Like Lumia 930 And Lumia 1520


Microsoft today announced Windows 10 Technical Preview for phones with very limited devices support. Specifically, Microsoft announced only low-end devices like Lumia 630. Many of us will have an obvious question of what happened to high-end devices like the 930/Icon or 1520. Microsoft provided the following reason,

Some context on why we chose these and not higher end phones like the 930/Icon or 1520: We have a feature that will be coming soon called “partition stitching” which will allow us to adjust the OS partition dynamically to create room for the install process to be able to update the OS in-place. Until this comes in, we needed devices which were configured by mobile operators with sufficiently sized OS partitions to allow the in-place upgrade, and many of the bigger phones have very tight OS partitions.

Note that this doesn’t mean that Windows 10 will take more disk space than Windows Phone 8.1, it’s just a function of the upgrade process at this point. Once the partition stitching feature is completed, many more devices will be supported.

If you are having a high-end Lumia device, sounds like you need to wait for some more weeks to get Windows 10 Technical Preview. Don’t get disappointed about not being able to install Windows 10 on your high-end device, read our post on the limited number of features in the current TP build.
