On: April 08, 2021

Using the WZT-UUP service, you can download UUP files directly from the official Microsoft servers and automatically create an installation ISO image of the final or any insider version of Windows 10 including cumulative updates too.

When Microsoft introduced the Unified Update Platform (UUP), the technology made it easy to create bootable Windows 10 ISOs for quick system installation.

Until now, special tools were required to convert UUP packages to ISO. Now, thanks to the WZT-UUP service, this process is automated as much as possible and allows you to independently build ISO distributions of the latest versions of Windows 10 ( final and insider ) online and in one click including Cumulative Updates.

Create an installation ISO image

  • Download to a separate folder and run the file - creatingISO_21354.1_en-us_amd64_professional.cmd multi_creatingISO_21354.1_en-us_amd64_professional.cmd - allows you to select additional actions when running the script:

    • Integrate additional language packs
    • Integrate .Net Framework 3.5
    • Create multi-revisions (all revisions)
    • Compress install.wim to ESD
  • Since this is a command-line script, Windows Defender SmartScreen will display a warning before launching - "Windows has protected your computer." Click More> Run Anyway. For safety, you can always analyze the contents of the script manually before running it.
  • Wait until the UUP packages are automatically downloaded from the official Microsoft servers and the installation ISO is created.
  • Use the generated ISO to install the latest version of Windows 10.
