SHA1 / MD5 hashes for Tech Bench ISOs

Hi guys,

I've been having unusual difficulty in downloading a good Windows 10 ISO from Microsoft Tech Bench. I must have tried four or five times, only for the download to apparently complete well short of its correct size, or for it to complete but fail to mount properly, or for it to apparently mount but for files on it not to copy properly ("invalid MS-DOS function").

My SHA1 checksums are varied, so presumably it's down to transmission errors.

Can anyone please confirm what the correct SHA1 hash is for the current ISO from Tech Bench, for the English International version, filename Win10_EnglishInternational_x64.iso?

Thanks!

you can try the media tool or download the actual esd used to create the iso

Thanks Kyhi. The media tool is not an option for me as I want to be able to use it for DISM. Would the ESD be suitable for my needs?

You can convert the media tool esd to wim with the tool from here: http://files.fm/down.php?i=cigfwdk&n...-WIM2ESD-4.zip

@khyi recommended it and it works fine - see ESD to ISO - Create Bootable ISO from Windows 10 ESD File - Page 45 - Windows 10 Forums

I don't have English international for the SHA though, sorry.

Mind if I offer a diagnostic? If continuing to have corruptions issues try a free Linux LiveCD or Live DVD Distro download. I use Linux Mint 17.2 from Linux Mint 17.2 "Rafaela" - Cinnamon (32-bit) - Linux Mint, the page has the MD5 code. Corruptions can occur via the transmissions but don't rule out it happening when writing to the hard drive, most downloads got to a temporary Folder before being completed by writing to the chosen Downloads Folder. To verify such downloads I use this small free utility:
MD5 SHA Checksum Utility - Free download and software reviews - CNET Download.com

Thanks everyone. I tried downloading again today, and this time the ISO I downloaded yielded a SHA1 hash of 3E4734DE476327F67D2E97CDEADEDB4BEA98623C. This matches a hash that I found listed on the MSDN website.

Since it's for 10240, though, and I'm trying to repair an installation of 10586, I don't know if it'll actually be any use.

EDIT: From my products.xml file, I'm now downloading what I think is the correct ESD file for English (United Kingdom), x64, Professional. Hope I'll be able to somehow use this either for DISM, or to perform a repair install of 1511.
