Last October, I wrote a post here for Win10.Guru entitled “A Peek Inside UUP dump.” It explains the origins and capabilities of the UUPdump.ml website (yes, indeed, it is hosted at a Malinese domain) . Simply put, this site builds scripts that use the same commands that WU uses on a PC to perform a Windows Upgrade to download all the component files. It then uses DISM and other tools to turn them into a complete, bootable ISO file. This works for any version you can find on the site, which does an excellent job of keeping up with current releases.
In fact, I’ve never visited UUPdump on the same day (even around the same time) that Microsoft releases a new Fast Ring Insider Preview without also finding it ready to hand you a script to build yourself an ISO for that version. Thus, I’ve learn to count on this site to take care of me. It hasn’t yet let me down. But there’s more…
This is the confirmation text from UUPdump that shows what it will get for you. Beneath this lies a button that downloads the ISO building script.

Head-to-Head, UUPdump Outspeeds WU
Recently, because of driver weirdnesses on one of my Fast Ring Insider Preview test PCs (a Lenovo X380 Yoga on which I conducted some graphics driver experiments I probably shouldn’t have) I’ve been using UUPdump a lot lately to keep up with upgrades. I’ve been running the regular upgrades through WU on another Lenovo (and older X220 Tablet) and through UUPdump on the afore-mentioned X380. This gives me an excellent side-by-side comparison as to how long it takes to get the job done one way or the other. In my recent experience, building an ISO through UUPdump and then upgrading from that ISO is at least 5 minutes faster than using Windows Update. That said, I do have a pretty fast Internet connection (usually runs 450-500 Mbps) so others may not have the same experience.
That’s nice, but what I like about UUPdump even more is that it builds an ISO for the upgrade every time. These come in handy should repairs or reinstalls of the same version ever be required. I just write them to my 64 GB Ventoy USB Flash Drive, so I can use them whenever I want to. It’s rare that you find something faster that also does more. I’m glad to recommend this as an upgrade approach to fellow Insiders who deal routinely with Fast or Slow Ring releases. Shoot! It also works for Feature Upgrades, too. I may just put it to work later this month when 20H1/2004 makes its debut. That way, I can download it only once, and use it to upgrade all 6 of my 1909 PCs.
