  10. Select mobile browser by clicking on “Custom…”.
  11. For example, you can select “Chrome iPad” or “Chrome
    Android”.
  12. You need to select a mobile device as your user agent
    because Microsoft offers the media files only when the website
    is accessed on a non-Windows 10 device.
    Change user agent
  13. Press CTRL + F5 to open the download center in your new
    user agent. Don’t close the developer window.
  14. If you followed the steps correctly, you’ll see the see

    Windows 10 May 2021 Update‘ .
  16. Select the language for your ISO.

    difference, so you need to be careful before downloading the
    files. You can verify the config from Settings > System >
    About.

You need to follow these steps because Microsoft’s download
center is designed to force Media Creation Tool when the
website is accessed on a Windows 10-powered PC.

When you follow the above steps, you’re making your web browser
pretend you’re using another operating system. As a result,
when you refresh the page in the browser after changing the
user agent, Microsoft’s site will offer you the Windows 10 ISO
instead of the Media Creation Tool.

If you followed the steps correctly, the download of the media
images will start and you can safely close the developer
window.

Method 2: Use the Media Creation Tool to create an ISO

The Windows 10 Media Creation Tool is also a great way way to
reinstall the operating system and it can download the
necessary files from Microsoft.

To download ISO using Media Creation Tool, follow these steps:

  1. On Windows 10, download the Media Creation tool from
    Microsoft’s
    website (under Windows 10 installation media section). It’s
    not a large download and it won’t take long to be finished

    Tool
    to upgrade the current installation or create a

How to use Windows 10 ISO file

Windows 10 21H1 ISO files can be used in a variety of ways. If
the Media Creation Tool and other programs are not working, you
can use it to manually install the operating system’s latest
update without losing files/apps.

Before getting started with the media file, you need to know
how it works.

An ISO image contains the installation files of Windows 10 with
the latest cumulative and feature updates.

On Windows 10, there are a lot of tools to open these media
files. However, you can always use File Explorer, which comes
with built-in functionality to mount ISO natively without the
need for extra third-party software.

To update your device to Windows 10 version 21H1 using ISO
files, follow these steps:

  1. Open File Explorer.
  2. Browse to the Downloads folder where the ISO image is
    located.
  3. Double-click
    Win10_20H2_v2_English_x64.iso” file to mount
    it.
  4. In the folder, double-click Setup.exe.
  5. Accept terms and conditions.
  6. Click on Upgrade this PC.
  7. The tool will now begin checking for quality updates, such
    as driver or cumulative update and it will be downloaded
    automatically.
  8. Select keep personal files, programs and apps option.
    You’ll be given options to keep everything, but you can choose
    to keep nothing at all and do a fresh install.
  9. When you’re sure about the selections, click ‘Install’ or
    ‘Next’ and the Windows 10 installation process will begin.
  10. Reboot.

Windows 10’s Setup.exe and Media Creation Tool are the two
easiest ways to complete the installation of any feature
update. Windows Update and Update Assistant Tools can sometimes
lag behind in rolling out newer versions, but there’s no
stopping when you download the update manually.

ISO file is also perfect if you want to clean install the OS or
build a USB flash drive to install Windows 10 on another
machine.

What is the size of the May 2021 Update?

In our tests, we observed that the size of the Windows 10 21H1
ISO is 5.8GB, which means it should not be downloaded on
metered/limited data connection. If you’re using your phone,
make sure that you’ve at least six gigabytes of bandwidth.

It’s also worth noting that the links will expire after 24
hours and the download won’t resume.

As always, you can skip the hassle of the media files and

download/install Windows 10 May 2021 Update using Windows
Update Settings or Update Assistant. This process is faster
when you’re running on the October 2020 Update (version 20H2)
because the update is based on the enablement package.
