Electronic Software Download (ESD) file is a file downloaded from Microsoft download application. This file format is usually used by Microsoft for sending upgrades to its Operating System and other software. ESD is encrypted and should be decrypted before we can see its contents. There are a few tools for decrypting ESD file and converting the ESD file to ISO easily.

There is a very popular command-line ESD Decrypter utility for converting ESD to ISO but we will not talk about that utility. Instead, we will discuss about graphically converting ESD to ISO which is easier and safer than the command-line.

Using Dism++ for converting ESD to ISO

Dism++ is a wonderful tool which gives a graphical user interface to Windows dism utility. Dism is a powerful command-line tool from Microsoft for different Windows operations like adding/removing Windows components, compacting the Operating System, installing/uninstalling Windows updates, backup and restore Windows system etc.

      For destination, you can select a folder and then give the name of ISO you want to create like :

      C:\Users\itechtics\Desktop\ConvertedWin10.iso

      After the conversion process, you will find ConvertedWin10.iso on Desktop.
