It sounds like you’re looking to get Windows 11 running on a specific device, but I need to clear up a few technical “wires” that often get crossed when talking about ARM64 and 32-bit systems.
The Compatibility Reality Check
To be direct: Windows 11 does not exist in a 32-bit (x86) version. Microsoft moved exclusively to 64-bit architecture with Windows 11. Furthermore, ARM64 and 32-bit are two different hardware languages. While you can download a Windows 11 ARM64 ISO for devices like a Surface Pro 9 (5G) or a Mac with Apple Silicon (via virtualization), it won’t work on old 32-bit processors. If you’re looking for a free, official offline installer to put on a USB, your best bet is the official Microsoft website or the Windows Insider Program, which provides the ARM64 VHDX or ISO files.With the general release of Windows 11 version 25H2, the completed ISO media may now be downloaded straight from Microsoft’s servers. Microsoft Insiders tested version 25H2 during the summer, and now the
RTM, an acronym for Released To Manufacturing, is an old-school Windows word that refers to the build that Microsoft will deliver to PC manufacturers for pre-loading onto new hardware with version 25H2 already installed. Although it is no longer used by Microsoft in public, the term RTM is still in use.
Microsoft released the basic build for version 25H2 of Windows 11 with the golden number 26200.6584.
The ISOs come in Home, Pro, and Education editions and are accessible in 38 languages. The average size of each ISO varies significantly, but it is approximately 7GB for x64 and a few hundred MB smaller for Arm64. These are useful for cleaning up your Windows installation or updating it to the most recent version.
