UUP Dump Downloader – How to Guide [2023]

UUP Dump Downloader is a Windows based Open Source program that provides you an easy way to download and save ISO images containing the latest build for Windows 10 operating systems.

UUP Dump Downloader uses Microsoft’s native update module, the “Unified Update Platform” (UUP), a unified update platform in order to reduce the size of latest build and installation time by selecting the right modules for the machine.

The UUP dump downloader project is an ISO tool via graphical user interface (GUI) which works through PHP + Autohotkey + CMD (bat.). The best thing about the UUP tool is that It automatically fetches the latest information from the server when it starts.

Note: Sometimes, Windows Defender recognizes the UUP downloader as Trojan virus and so It blocks the program. Some antiviruses like Sophos, BitDefender, F-Secure, GData also find it harmful to the system. However, Avira, Kaspersky, Avast and Malwarebytes find it very clean.

Lets see the step by step guide:

How to download and install UUP dump downloader

The project has been discontinued. Only the official website is supported and the required modules are updated. However, you can still download and install the UUP dump downloader by following the below step by step guide. The downloader is not a default exe file. It is a bat file containing the command line program as the downloader uses the functionality of autohotkey.

That’s it.

You can use this ISO image to burn a bootable DVD or a USB drive. There are several windows applications available such as Rufus which provides you an easy to use user-interface to burn a bootable pendrive.

Final Words

UUP dump downloader is one of the best and most popular windows 10 ISO downloaders which is used by most of the geeks. It saves you time and provides you an easy to use user-interface to download all the big amounts of chunks into your folder with ease.

Some of the antivirus block the UUP as they recognize it as a trojan virus. If your antivirus also blocks it, then I would recommend you turn off the antivirus for sometime or until the UUP ISO downloader downloads the latest build from the server. Once the file gets downloaded, you can again turn on the antivirus.
