Microsoft Expands the Use of New Update Delivery Tech in the Windows 10 Insider Preview

Microsoft on Thursday announced that is expanding the availability of its Unified Update Platform (UUP) update delivery technology in the Windows 10 Insider Preview.

“We are excited to begin releasing PC builds to Windows Insiders using differential download packages,” Microsoft’s Bill Karagounis writes in a new post to the Windows Experience blog. “Windows Insiders have been running the UUP bits for a while now and are already experiencing the benefits of differential packages.”

Confused? I got this one.

As you may recall, UUP promises to dramatically reduce the size of the updates—major or minor—that Microsoft delivers to Windows 10 going forward by using differential download packages. And while this was always going to be a change for after the Creators Update, Insiders started getting UUP-based updates in December 2016.

But that was only for smaller, monthly updates.

Starting this week, Microsoft is turning on UUP for full build downloads to the Insider Preview, or what it calls canonical download packages. These are the equivalent of full version upgrades, like the Creators Update. Meaning that once the Creators Update is deployed publicly, future Windows 10 updates—which happen frequently—and full version upgrades—starting with Redstone 3 in late 2017—will utilize UUP.

Why, you ask? The reasoning hasn’t changed: These UUP-based updates and upgrades promise to be up to 35 percent smaller than the updates and upgrades that Microsoft has been delivering to Windows 10 so far.

    The UUP updates will be smaller than the current updates, thus making the update process quicker. Will the UUP updates be inherently faster in themselves as well?

      In reply to johnlavey:

      You have to understand that only the DOWNLOAD will be smaller and quicker. Installation of the update should not be any less and might even take a bit longer. It actually builds a a Windows image from your current OS system files and downloaded files and does an actual update like it always did; i.e. install and migrate, and move the old OS in windows.old folder.

    Was 14046 delivered as a UUP download? It seemed much smaller than 15042.

    This is good news. Especially for those on a connection with Dish Network.

    Updates on a diet?  Can't wait, seriously can't wait as downloads take way too long as it is.

    we'll they've not done it for the latest mobile update, my phone says the download is 7.68GB! think I'll wait until I'm on wireless...

    I don't know about the size, but the time taken to apply the updates hasn't decreased as far as I can tell!

    I got the 15048 build and it still took 35 minutes on my box to apply the update.

    My box is not slow, Core i5 at 3.0GHz, 32GB RAM, 256GB SSD for C: drive.

    Unless it wasn't in this build?
