Source Code | Documentation | Third party libraries | Downloads

Readme

UUP Media Creator is a set of tools designed to help you scan, fetch updates from Microsoft own Unified Update Platform (UUP), and allow you to create medium out of it when an appropriate tool does not exist in the wild.

Right now the tooling includes:

• UUPDownload: Allows you to scan, fetch and download updates from UUP (Windows Desktop, Windows 10X, Windows Holographic, Windows Server, Windows Mobile, Windows IoT etc...)
• UUPMediaConverter: Allows you to convert a downloaded UUP update for Windows Desktop into an usable ISO image to use in last decade DVD reader or simply mounted.

TIP 1: You can append -e [Edition to download] to get the files needed only for a specific edition

TIP 2: You can append -l [Language to download] to get the files needed only for a specific language

Important

The -v is not used to specify which version of Windows you want to download! The parameters used by UUPDownload above are used to tell Windows Update which version of Windows you are currently running. Therefore, the -v parameter is used to tell Windows Update your current version of Windows. You will never get versions lower than the value specified in -v and some requests may also never get you the version specified in -v but only newer. If, however, you want to download a very specific version using -v then you must use the -y option to tell Windows Update you only want this version.
