Windows 10 build 10240 (th1)

This is the first consumer build which is an official RTM of Windows 10.0 "Threshold". It is the first build to become available for consumers to install and was also available as a free upgrade for Windows 7 and Windows 8.1 users until 2016-07-29. This build was released on 2015-07-15 to Windows Insiders and became the final build of the TH1 cycle on 2015-07-29. Microsoft (as of 2015-08-16) is still developing revisions of the base 10240.16384 build to incorporate bug-fixes, despite having recently begun development of Threshold Wave 2, the next stage in Windows 10's continual evolution. It contains very few changes over build 10176, a leaked RTM candidate, however, it does include several changes over 10166, the last preview builds in the Threshold Wave 1 release cycle. These changes are:


 * Watermark has been removed.
 * Widespread stability improvements
 * Branch change from fbl_impressive to th1

Aside from these changes, 10240 is a build which contains only limited changes over previous builds.
