Getting Windows images

There is currently only one legal way of obtaining Windows 10 ARM64 images: download the UUP files directly from Microsoft servers and build an ISO from them.

There are two websites that can do that for you: UUPDump or

We strongly recommend using UUPDump as its scripts are more reliable than those from rg-adguard.

For Linux and macOS, UUPDump is the only option.

Downloading an ISO image using UUPDump

  1. Go to

  2. Choose the release type (click on arm64): Screenshot%202021-04-13%20193153 The description of each release type will help you find the right build for your needs.

    • If you want a stable system, the "Latest Public Release build" is the way to go.
    • If you need x64 app support and other cutting-edge features, then you'll find them in the "Latest Dev Channel build".
  3. Select the build of Windows: Screenshot%202021-04-13%20205559 We've selected "Latest Public Release build" in the previous step. If multiple versions appear (like in the screenshot above), it's recommended to select the latest one. That is 19042.928 in our case.

  4. Select your language: Screenshot%202021-04-13%20211241

  5. You may want to unselect the edition that you don't need here: Screenshot%202021-04-13%20212437

  6. Click on "Create download package": Screenshot%202021-04-13%20213223

  7. Extract the downloaded archive to a location that doesn't have spaces

    • D:\Downloads\19042.928_arm64_en-us_multi_0287ae95_convert (Windows)
    • /home/username/Downloads/19042.928_arm64_en-us_multi_0287ae95_convert (Linux)
  8. Run the ISO download script and wait until it prompts you to press 0 or says Done.

    • in Windows, double-click on uup_download_windows.cmd then press Yes in the User Account Control dialog
    • in Linux / macOS, open a Terminal window and run bash or bash
      You may be asked to install some dependencies. If you cannot find them in the package manager of the OS, you'll have to build and install them from source code. We won't cover this process here as it can slightly vary from distro to distro, and it's beyond the scope of the guide. More details can be found on the internet.

    This process may take a long time, depending on the speed of your internet connection, CPU and storage.

    If it fails, redownload the script and try again. In case this still doesn't solve the issue and you're not able to figure out the cause, you could try joining the UUPDump Discord server linked in the header of their website and asking for help there. Alternatively, you can try using instead. (Windows-only)

  9. The ISO image can be found in the same directory as the download script.
