Windows 10 build 9926

This build is the January Technical Preview, released to the public on 2015-01-23. It is the first preview build to include features such as Cortana, Continuum and Office Touch apps. Several apps, including PC Settings, Voice Recorder, Alarms and Xbox received major updates. Many of the features demoed at the January 21st event were included in this build. Notably missing features include Project Spartan, streaming functionality in the Xbox app and Outlook Mail and Calendar.

The first indications of Microsoft's final edition names have also been included in this build. Cortana is missing several features shown in the demo, most notably the capability to send emails using the assistant. The new XAML-based Start menu in this build is also missing key functionality, such as Jump Lists. Observant users will note that the transparency shown in several of the demos at the Jan 21st event is not including in this build.

Build 9926 is the first public build to be from the fbl_awesome1501 build branch, a replacement for fbl_release. It is also quite possibly the last, as no new builds have been compiled in this branch since January 30th.
