Microsoft provides various ways to download Windows 11 ISO files, suitable for users who need to reinstall the system, create a boot disk, or install a virtual machine. If you just want to upgrade the current system, you don’t need to manually download the ISO, but if you do have the need to obtain the original image file, the following method can be operated directly from the official website.

Using Microsoft's official media creation tool

Microsoft provides a program called "Media Creation Tool", which can help you download Windows 11 ISO and create a USB drive boot disk.

• Open the Microsoft Windows 11 download page and click "Download Tool Now".
• Run the downloaded tool (MediaCreationToolWx.exe), and after accepting the license terms, select "Create installation media for another computer".
• Set the language, version, and architecture (usually 64-bit), and select "ISO File" as the output method.
• The tool will automatically download the corresponding version of ISO and save it to the location you specified.

This method is the most direct and ensures that you get a genuine pure system image.

Manually select version via Microsoft Software Download Center

If you need a specific version of Windows 11 (such as Home, Professional, or different language versions), you can bypass the tool and go directly to the download center:

• Visit Microsoft's software download center , search for "Windows 11" and enter the corresponding page.
• Log in to your Microsoft account (if not, you can register a free account).
• According to the prompts, select the system version, language and other information you need, and the system will generate a download link.
• Click to download to get the ISO file.

This method is more suitable for advanced users who have clear requirements for the system version.

Verify the integrity of ISO files

After downloading ISO, it is recommended to verify the hash value of the file to ensure that it is not corrupted or tampered with:

• The Microsoft download page usually provides SHA256 value, which you can compare using command line or third-party tools such as Microsoft File Checksum Integrity Verifier or PowerShell.
• For example, enter:

   CertUtil -hashfile file path SHA256

• Compare the output results with the hash value provided by Microsoft, and the consistent explanation file is no problem.

This step is easy for many people to ignore, but it is very important in a safe and sensitive scenario.

Basically that's it. The whole process is not complicated, but be careful to choose the correct version and language, otherwise it may affect subsequent installation.
