How to Create Bootable ISO from Windows ESD File
The ESD files that Microsoft uses to ship Windows 10 new builds allow anyone to create new ISOs. No new ISOs have been provided because it wants user to try out the upgrade path.
When Windows 10 Technical Preview is upgraded to a new build using the PC Settings Download & Install method, Microsoft uses the ESD file format to deliver install files needed. ESD stands for Electronic Software Delivery, the Windows install.esd file contains the usual Windows install.wim file (WIM = Windows Imaging), encrypted and compressed. Install.wim file in its turn contains everything needed for a complete Windows installation.
This tutorial will show you how to create a bootable ISO file from the install.esd file you have downloaded which can then be burned to a DVD disk or USB to be used for clean install instead of upgrade.
This tutorial is made to be used with Windows 10 Technical Insider Preview build upgrades and will be updated when possible Windows 10 Consumer Preview will be available, and again when Windows 10 final build is released.
Windows Update TH2 Pro Build 10525 is the first build released since RTM Build 10240 was shipped out in July

TH2 Pro Build 10525 will be my example on this post.
OK lets Start!!
When a new build is available download it, install if you want to use it on the same computer. Installing is not necessary to create an ISO file as told in this tutorial, the files needed are available after downloading them..
Located on your Drive C:\$Windows.~BT\ If you can NOT see this enable show hidden folders. Make sure you have the install.esd file inside the C:\$Windows.~BT\Sources\ if not click and check Windows update again.
1. Download The ESDtoISO tool is based on ESD Decrypter v.6.7. Download the tool (ESDtoISO.zip) from OneDrive: bit.ly/TenForums
or Google Drive : http://adf.ly/1N2Oll
2. Disable any AV program. You can enable it again after the ISO file has been created. Make sure that the ESD file is not read-only or blocked. Extract this package to a folder, naming the folder as you wish.
3. Right click on ESDtoISO.cmd and select Run as administrator. You will be prompted to enter the ESD file path. For instance, if your ESD file is INSTALL.ESD and it is located in Z:\Downloads, enter Z:\Downloads\INSTALL.ESD or on my BMT tuts this where the file usually found C:\$Windows.~BT\Sources\INSTALL.ESD
4. Select the ISO you want to create, a traditional ISO which contains the install.wim (recommended) file to install Windows, or an ESD based ISO which instead of install.wim file contains the compressed install.esd to install Windows. Both types can be used the same way to install Windows, both can be used as such, mounted to a virtual drive or burned to Flash or DVD drive.
5. The tool starts working, showing an error for missing key. This error can be ignored:
6. The process can take some time, up to half an hour depending on your hardware. When finished you have an ISO image to be used as such in installing the new build on a virtual machine or to be burned to DVD or USB to be used on a clean install on a physical computer.
