How to download a Windows 10 21H2 ISO from Microsoft

Microsoft released Windows 10 21H2, the November 2021 update last week, and you can now download an ISO image for the new version to set aside for emergencies or clean installations.

Windows 10 21H2 is not a very significant feature update and only contains a few new features for business users and increased protection against WiFi side channel attacks.

However, if you are planning to upgrade to the new version of Windows, it is always recommended that you download or create a handy ISO image to troubleshoot issues or perform fresh Windows installations.

Why should you download an ISO image

An ISO image is a sector-by-sector copy of a DVD or other media stored in a single file. As this file is a replica of the original media, it can then be written (burned) to another DVD or USB stick in the same way it was created.

Using ISO allows you to create DVD and bootable media backups in case you lose the original media and need to recreate it. ISO images can also be mounted as drive letter in Windows or virtual machines or extracted by programs such as 7-Zip to access the files contained.

ISO images are particularly useful for performing “clean” installations of Windows, which is a fresh installation of the operating system without any of your previously installed programs, data, or configuration settings.

Finally, ISO images can be used to create bootable USB drives that can be used to access the Windows recovery environment if Windows does not start correctly, diagnoses crashes, or removes a particularly stubborn malware infection.

For this reason, it is recommended that all users download the latest Windows 10 ISO as new feature updates are released.

How to download a Windows 10 21H2 ISO from Microsoft

To create a Windows 10 21H2 ISO, you can use two different methods.

The first and easiest method is to use the Media Creation Tool (MCT) to create the ISO. However, it takes longer because the tool has to download files and convert them to ISO.

Those who don’t want to wait for the MCT to create the ISO can download it directly from Microsoft by tricking their site into thinking you are downloading from a mobile device.

These two methods are explained below.

Microsoft offers the Media Creation Tool that lets you download the latest Windows 10 ISO image to a file or burn it to a bootable USB drive.
