Windows 10 build 10240 (th1)

This is the first consumer build which is an official RTM of Windows 10.0 "Threshold". This build was released on 2015-07-15 to Windows Insiders and became the final build of the TH1 cycle on 2015-07-29. 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. 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.
