UUP Dump Downloader is an open source program for Microsoft's Windows operating system to download Windows 10 ISO images that include the latest updates for the operating system.
Windows Defender does not like the program and blocked the download claiming that it included a Trojan. The security application is not the only one that flags the executable as malicious; the security engines of BitDefender, GData, F-Secure, Symtance or Sophos flagged it as well while Avast, Avira, ESET, Kaspersky, or Malwarebytes returned a clean rating.
The most likely reason for the flagging is the use of Autohotkey.
Most antivirus engines that flag it use a generic flag for the application which is usually an indicator that it is a false positive. Still, you may want to run the program in a virtual machine or sandbox, or ignore it for the time being until it is resolved.
You can run the program right after download, it does not need to be installed. The interface is simple: pick a Windows 10 build that you want to download and create an ISO from, and select the desired language, edition, and local save location. Check the "save UUPs to "UUPs" directory" and "Skip UUP to ISO conversion" boxes if you just want to download the UUP and don't need the ISO image.
UUP is Microsoft's Unified Update Platform which the company introduced in 2016.
The application supports stable builds but also Insider Builds and Windows Next builds.
A click on "start process" begins the download of the selected build. Note that you may receive a "build is no longer available" notification if the selected build can't be downloaded anymore or if the connection is blocked by a firewall.
UUP Dump Downloader opens a command prompt window which lists each step of the process. The application downloads the files from Microsoft.
The download may take a while to complete and you may monitor the progress as everything is echoed by the command prompt window.
The application may integrate updates released after the build was released as well; happens if you select release updates and not Insider Builds.
UUP Dump Downloader uses the Deployment Image Servicing and Management tool (DISM) to process the downloaded files.
UUP Dump Downloader is an easy to use program to create up-to-date Windows 10 ISO images that include feature updates and integrate updates released afterward.
The application has a few downsides at the time of writing. The flagging by antivirus engines is probably the major one as it will prevent wider distribution as users may not want to run the program or add an exception for it to run it.
UUP Dump Downloader could have a better selection menu; an option to hide Insider Builds would be useful to make it more accessible. It would also be handy if the user could decide whether updates should be integrated or not.
