As for an emulator release, it’s a testable build of the Windows 10 mobile platform designed for use on a PC only, unfortunately. However, Windows 10 Mobile fans with PCs can now get a quick look and feel for what is believed to the final build before its pushed to Windows phones out in the wild.
Much of Windows 10 Mobile is complete, as far as significant feature implementation, but bug fixes and optimizations tend always to be a welcomed commodity.
Given the various bugs and issues with the general Win10 x84/x64 PC releases being posted and experienced i'll hold off updating my windowsphone for the foreseeable few months.
