- 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.
- Use the Windows key + I keyboard shortcut to open the Settings app.
- Click Update & security.
- 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.

- Right-click the file and click Run as Administrator.
- In the ESD Decrypter Script user interface, type 2 to select the Create full ISO with Compressed 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.
