Looks like Windows Phone users will have to wait a tad longer for Microsoft’s latest Windows 10 software update to arrive on their smartphones. Microsoft is planning a mega release of its all new operating system called Windows 10 after 3 long years and has been releasing build after build for user testing. The upcoming OS for PCs is lined up for a summer release, however, its version for mobile devices may need another 2 months of testing before final version is released. Microsoft’s Joe Belfiore announced the delay at a media event at Windows Build 2015 in San Francisco. He explained that Microsoft was adapting Windows 10 for PC experiences before smartphone experiences and that as of now the launch date has not been decided. Not that Microsoft is going slow with the build releases for Windows 10. It has already released the latest build 10074 but major changes are expected in Windows 10 build 100120. The Windows 10 Build 100120 is supposed to feature live 3D tiles in the Start Menu to make the user experience more interesting. Microsoft has already released Windows 10 IoT Core version for Internet of Things devices and Raspberry Pi 2, MinnowBoard Max and Intel Galileo.
