Create installation media for Windows

You can use installation media (a USB flash drive or DVD) to install a new copy of Windows, perform a clean installation, or reinstall Windows 10.

To create installation media, go to the software download website, where you’ll find step-by-step instructions. On that website, you can select a version of Windows and create your own installation media using either a USB flash drive or a DVD. To go directly to one of the versions, select one of these links:

Windows 10 (Then select Download tool now.)

Important: Back up your files before you install or reinstall Windows on your PC. Learn how for Windows 10 or for Windows 7 and Windows 8.1.

To create the installation media, here’s what you’ll need:

A PC with a reliable internet connection. The download time will vary, depending on your internet connection.

A USB flash drive or DVD. A blank USB flash drive with at least 8 GB of space, or a blank DVD (and DVD burner). We recommend using a blank USB or blank DVD because any content on it will be deleted. When burning a DVD from an ISO file, if you’re told the disc image file is too large, you’ll need to use dual layer (DL) DVD media.

A product key. Your 25-character product key (not required for digital licenses). For help finding it, go to Find your Windows product key.

After you’ve created the installation media, you can reset or reinstall Windows. To learn more, go to Recovery options in Windows 10.

How to create a Windows 10 ISO file using an Install.ESD image

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.

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

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.

On Windows Update, click Check for updates and let the latest version download to your system.

  • 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.
  • Click This PC from the left pane.
  • Double-click the Windows installation drive — Usually the C: drive.
  • Click the View tab on File Explorer.
  • Check the Hidden items option to see the $WINDOWS.

    BT the folder that contains the installation files.

    Open the $WINDOWS.

    BT and inside the Sources folder, right-click and copy the Install.ESD file.

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

    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.

  • Select which media you want to use:
    • USB flash drive. Attach a blank USB flash drive with at least 8GB of space. Any content on the flash drive will be deleted.
    • ISO file. Save an ISO file to your PC, which you can use to create a DVD. After the file is downloaded, you can go to location where the file is saved, or select Open DVD burner, and follow the instructions to burn the file to a DVD. For more info about using an ISO file, see Additional methods for using the ISO file to install Windows 10 section below.
  • After the installation media is created, follow the steps below to use it.

    After completing the steps to install Windows 10, please check that you have all the necessary device drivers installed. To check for updates now, select the Start button, and then go to Settings > Update & Security > Windows Update, and select Check for updates. You may also wish to visit your device manufacturer’s support site for any additional drivers that may be needed.

    Note: Drivers for Surface devices may be found on the Download drivers and firmware for Surface page.

    Before you install Windows 10, it’s a good idea to save any work and back up your PC before you start. If you used the media creation tool to download an ISO file for Windows 10, you’ll need to burn it to a DVD before following these steps.

    1. Attach the USB flash drive or insert the DVD on the PC where you want to install Windows 10.
    2. Restart your PC.

    If your PC does not automatically boot to the USB or DVD media, you might have to open a boot menu or change the boot order in your PC’s BIOS or UEFI settings. To open a boot menu or change the boot order, you’ll typically need to press a key (such as F2, F12, Delete, or Esc) immediately after you turn on your PC. For instructions on accessing the boot menu or changing the boot order for your PC, check the documentation that came with your PC or go to the manufacturer’s website. If you do not see the USB or DVD media device listed within the boot options, you may need to reach out to the PC manufacturer for instructions for temporarily disabling Secure Boot in your BIOS settings.

    If changing the boot menu or order doesn’t work, and your PC immediately boots into the OS you want to replace, it is possible the PC had not fully shut down. To ensure the PC fully shuts down, select the power button on the sign-in screen or on the Start menu and select Shut down.

  • On the Install Windows page, select your language, time, and keyboard preferences, and then select Next.
  • Select Install Windows.
  • If you downloaded an ISO file for Windows 10, the file is saved locally at the location you selected. If you have a third-party DVD burning program installed on your computer that you prefer to use for creating the installation DVD, that program might open by going to the location where the file is saved and double-clicking the ISO file, or right-click the ISO file, select Open with and choose your preferred DVD burning software.

    If you want to use the Windows Disk Image Burner to create an installation DVD, go to the location where the ISO file is saved. Right-click the ISO file and select Properties. On the General tab, click Change and select Windows Explorer for the program you would like to use to open ISO files and select Apply. Then right-click the ISO file and select Burn disc image.

    If you want to install Windows 10 directly from the ISO file without using a DVD or flash drive, you can do so by mounting the ISO file. This will perform an upgrade of your current operating system to Windows 10.
