Just leaked Windows 10 build 10176, which is generally referred to as the first RTM Candidate (RTM candidate). The leaked version is in English and is released in ISO format.
There is currently no more information about this build.
Yesterday we mentioned that after the release of the Chinese version we will see very soon the English build, from which we will publish the download links.
Build 10176 is ultimately the first RTM candidate, and so it's fairly stable and reliable.
Recall that RTM was originally scheduled for this weekteam, but sources within the company said that Redmond is looking at the middle of next week as a possible release date.
Before you start downloading the ISO you should know that it is custom made, i.e. made by a user who changed language on the ISO of the Chinese version that was leaked earlier.
The file name is 10176.16384.150705-1526.TH1_CLIENTENTERPRISE_VOL_X64FRE_EN-US.ISO.
Proceed with your own responsibility.
