Microsoft released Windows 10 21H2, the November 2021 Update, last week and you can now download an ISO image for the new version to put aside for emergencies or clean installs.
Windows 10 21H2 is not a very large feature update and only contains a few new features for business users and increased protection against WiFi side-channel attacks.
However, if you plan on upgrading to the new version of Windows it is always recommended that you download or create an ISO to have on hand for troubleshooting problems or performing clean installs of Windows.

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 key in the same way it was created.
Using ISOs allows you to create backups of DVD and bootable media in the event that 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 like 7-Zip to access the contained files.
ISO images are particularly handy for performing “clean” installations of Windows, which is a fresh install 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 boot properly, diagnose crashes, or remove a particularly stubborn malware infection.
Due to this, it is recommended that all users download the latest Windows 10 ISO as new feature updates are released.
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, this takes longer as the tool needs to download files and convert them into an ISO.
Those who do not 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.
Both of these methods are explained below.
Microsoft offers the Media Creation Tool that lets you download the latest Windows 10 ISO to a file or burn it to a bootable USB drive.
To download the Windows 10 21H2 ISO using the Media Creation Tool, please follow these steps:

You will now have the latest Windows 10 21H2 ISO image file saved to the selected folder, which can be used for virtual machines or to create bootable media later.
When you go to Microsoft’s “Download Windows 10” page, you are given the option to update via Windows Update or to download the Windows 10 Media Creation Tool.
Below, we will provide a method that tricks Microsoft into offering an ISO image file for Windows 10 21H2 instead.
