For business users, the 21H2 ISO is available via the VLSC or through Visual Studio Subscriptions (formerly MSDN). Installation and Activation
Once you have the ISO, you can use tools like Rufus to create a bootable USB drive.
Format: Ensure the drive is formatted to GPT for modern UEFI systems. win1021h2englishx64iso microsoft
