Windows 10 build 14366 was released as we mentioned in the morning, for Windows Insiders, but official ISO images will not be made available by the company as it is a build for Fast Ring. Below we will see how you can create your own ISO images from scratch.
First, you need to download the Windows 10 build 14366 ESD files. Direct links are available below thanks to WzorNet:
Window 10 build 14366 ESD files
Choose a file that represents the version you want. For example, the file for Window 10 build 14366 PRO x64 in English is:
14366.0.160610-1700.rs1_release_CLIENT PRO_RET_x64fre_en-us_3df8f3c5edd383e6b49a600f5e9a76da85fb7e1e.esd.
Download the file to computer you.
Then download ESD Decrypter from the following link:
ESD Decrypter
Export the ESD Decrypter to any folder and place the ESD file in the same folder.
Now right click on the decrypt.cmd file and run it as Admin . 
When you open it blue window, type 1 and press enter to start creating the ISO.
Sit comfortably and wait until the procedure is over.
