On Windows (Command Prompt as Admin):
certutil -hashfile C:\Downloads\Win11_ARM64.iso SHA256
On macOS (Terminal):
shasum -a 256 /Downloads/Win11_ARM64.iso
On Linux:
sha256sum /home/user/Win11_ARM64.iso
If you have downloaded an ISO and want to ensure it is "verified" and safe to use, do not just trust the filename.
If you are writing a tutorial, always include this checklist:
| Check | Status |
| :--- | :--- |
| File extension | .iso (Not .exe or .zip) |
| Architecture in name | ARM64 |
| Size | ~5 to 6 GB (Not 800MB) |
| Source URL | https://www.microsoft.com/software-download (HTTPS only) |
| Hash match | Compare SHA256 to official value | microsoft windows 11 arm iso verified
If you own a device like the Lenovo ThinkPad X13s or Microsoft Surface Pro 9 5G, your OEM provides a recovery image. These are technically verified but locked to specific hardware.
What to avoid:
The most reliable way to get a verified, bootable ARM64 ISO is via the Windows Insider Program. Microsoft releases fresh ARM builds here weekly. On Windows (Command Prompt as Admin): certutil -hashfile
Now that you have a legitimate ISO, here is how to use it on different hardware.
⚠️ Important: Microsoft does not publicly distribute a standalone Windows 11 ARM ISO for general download on the standard Windows 11 download page. You must access it through official channels.
Unlike the standard x86 version, Microsoft does not offer a simple public download page for the Windows 11 ARM ISO. You must obtain it through one of these official channels: On Linux: sha256sum /home/user/Win11_ARM64
