Earlier this week, Microsoft"s Gabe Aul announced that no Insider build should be expected for Windows 10 Mobile or PC before the company"s October 6th event. However, he did inform users that build 10550 is being tested for PC and just a few days ago, new screenshots for build 10551 leaked, revealing enhancements for Microsoft"s Edge browser. But things have been pretty quite on the Mobile front with the most recent build, 10536.1004, being released almost three weeks ago. Today, Gabe Aul has stated that Windows 10 Mobile build 10559 is currently being tested for the Fast ring internally.
