Instructions: Create a bootable ISO file using ESD Image for Windows 10 Build 10049

None of the 4 links to build 10049 work yet.

Keep trying periodically.

Please note, only US English is available at this time. I will update this thread with access to other languages. Also note, these links might not be live yet. I am not trying them, because I don't want to eat up my bandwidth by opening the link (metered connection). IE has a tendency to anticipate a download.

If you can't wait on Microsoft to push .ISO files to testers for build 10049, you can create yours now:

Download the desired edition and architecture from the following link:

• Windows 10 Pro x86 build 10049
• Windows 10 Pro x64 build 10049
• Windows 10 Enterprise x86 build 10049
• Windows 10 Enterprise x64 build 10049

For persons requesting other languages, see the following thread:

I will update this link when they become available.

Download ESD Decrypter 4.7 (esd-decrypter-wimlib-4.7z)

You can use NTLite as an alternative to convert the .ESD file into a .ISO:

https://www.ntlite.com/

Extract esd-decrypter-wimlib-4.7z to a folder.

Put the appropriate .ESD file you downloaded into that same folder.

Right click decrypt file in the same folder and click Run as administrator

Select option 1

Hit Enter

Wait

When complete, burn to a blank DVD or create a bootable copy on a USB thumbdrive.

See article for instructions how to do that.

Persons have recommended using Rufus for best results when creating a bootable copy on a USB thumb drive.

Waiting for the spanish version

Try using the Windows 10 ESD DB to locate your language.

Then copy:

http://b1.download.windowsupdate.com/c/updt/2015/03/

adding File_Name followed by Hash.

10049.0.150325-1700.fbl_impressive_CLIENTPRO_RET_x64fre_es-es.esd

105C492C3F763B75E3BB8BF2C0E6082B4DF09A6F

Move .ESD to end of URL

Separate language and hash with underscore

May work eventually. I'm trying with en-gb

Doesn't work

Hi,

I'm trying to download the 10049 esd file for x64 Pro, but that link does not seem to work anymore...

Hi Andre--

What about using this process on the install.esd file that lands in the c:\$Windows.~BT directory ?  It created an .iso file for me called en_windows_10_enterprise_10049_x64_dvd.iso but I am having difficulty creating the bootable USB with rufus-- threw an error twice about not being able to extract from the ISO.

Any thoughts ?

Try using 7-zip to extract the iso to your flash drive.

I did it the way you are suggesting, but for the Windows 10 Pro Build 10049.  I used the Windows 7 USB DVD Download Tool to create the USB stick from the ISO and it worked to install 10049 on another computer.

Dear sir,

I found that link service unavailable
