Do You Need A Dmg File For Install Windows 10

When you need to do a clean install or upgrade to Windows 10, similar to previous versions, Microsoft provides the installation files through a new ESD (Electronic Software Delivery) image format, which is commonly available via Windows Update.

We know this image as the install.ESD file, which is around 3GB in size and contains everything that is needed to install the operating system from scratch. Windows Update will typically download this ESD file plus other files to the $WINDOWS.~BT hidden folder on your computer.

The benefits of the Install.ESD is that it's an encrypted and compressed version of the Install.WIM image, thus making the download faster and more secure, which also results in spending less time during an upgrade.

While Microsoft makes publicly available the files to install Windows 10 through the Media Creation tool and via Tech Bench upgrade program, the software giant typically doesn't offer the ISO files to install the latest Insider preview builds released in the Fast ring. However, you can use an ESD image to create an ISO file that you can use to do a clean install or upgrade of the latest version of Windows 10 on one or multiple computers.

In this Windows 10 guide, we'll show you the steps to convert an encrypted image into an ISO file.

How to create an ISO file of Windows 10 with the Install.ESD image

When a new Insider preview build becomes available, do the following.

  1. Download the ESD Decrypter command-line utility using this link.

    Warning: While this command-line utility is known to work successfully, it's still a third-party tool, use it at your own risk.

  2. Uncompress the utility to an empty folder on your desktop.

    Note: If you can't open the .7z file to uncompress the utility, you can use popular 7zip tool, which can be downloaded here.

  3. Use the Windows key + I keyboard shortcut to open the Settings app.
  4. Click Update & security.
  5. On Windows Update, click Check for updates and let the latest version download to your system.

  6. When the new installation files are ready, and you're asked to restart to begin the process, use the Windows key + E keyboard shortcut to open File Explorer.
  7. Click This PC from the left pane.
  8. Double-click the Windows installation drive -- Usually the C: drive.
  9. Click the View tab on File Explorer.
  10. Check the Hidden items option to see the $WINDOWS.~BT the folder that contains the installation files.
  11. Open the $WINDOWS.~BT and inside the Sources folder, right-click and copy the Install.ESD file.

  12. Open the folder where you extracted the ESD Decrypter utility files, right-click, and paste the Install.ESD file on this location.

  13. Right-click the decrypt.cmd file and click Run as Administrator.
  14. In the ESD Decrypter Script user interface, type 2 to select the Create full ISO with Compressed install.esd option and press Enter to begin the process.

Once the process completes, you'll end up with ISO file inside the ESD Decrypter folder with a descriptive name and build number (e.g., en_windows_10_pro_14316_x64_dvd.iso).

You can now use this file to install Windows 10 on a virtual machine, or you can use a tool like Rufus to make a bootable installation media.

It's important to point out that there are different versions of the ESD Decrypter tool, but version 4.7 continues to work with the latest Windows 10 Insider Preview. You will also find other similar tools around the internet, such as ESD-Decripter, that are based on the command-line tool we're mentioning in this guide.

Note: The nature of dealing with an encrypted file makes the tool useful as long you're using the correct RSA key to do the decryption. While the RSA key comes integrated in the ESD Decrypter tool, Microsoft can begin to ship a new version of Windows with a different key at any time, which can make the tool unusable unless you provide a new key.

What is a DMG file?

A DMG file is a mountable disk image used to distribute software to the macOS operating system. The file is typically downloaded from the Internet by a Mac user, then double-clicked to install an application on the computer.

Today, software developers typically build and distribute applications for Mac users as DMG, .APP, or .PKG files. DMG files are especially common since their contents can be verified upon installation to ensure they have not been tampered with and they can also be compressed to reduce the size of the installer.

When a Mac user downloads a DMG file, he can simply double-click it to open it with the DiskImageMounter utility that comes with macOS. When the DMG file is opened, it mounts a virtual disk on the desktop and in an Apple Finder window as if it was a CD or a USB flash drive that was just inserted into the computer.

In the Finder window, the Mac user can double-click the program icon, which is an APP file, to run the app. Or the Mac user can drag the program icon to the 'Applications' folder icon to move it to the 'Applications' directory in macOS.

After the software stored in the DMG file is installed, the DMG file is no longer needed. Therefore, DMG files can be deleted after installing the software.

While DMG files are Mac-specific and not intended for use in Windows, there are several Windows programs that can extract their contents or convert them to other formats. Some programs include 7-Zip, PeaZip, and DMG2IMG.

NOTE: The DMG format replaced the .IMG file format, which was previously used in Mac OS Classic.
