Id say so as the UUP dump doesn't download from the servers

Unable to retrieve data from Windows Update servers. Reason: EMPTY_FILELIST
If this problem persists, most likely the set you are attempting to download was removed from Windows Update servers.

My bad. I just realized I had to join the Insider Release Preview to download this one. I haven't been until now. I read above that it is precisely RP and now it's downloading.👍:giggle:

26H1 has been working awesome on both my Lenovo ThinkPad X1 Carbon Gen 12 and Lenovo P3 Ultra.

In the previous build, I was having an issue where the display brightness nor the volume bar was popping up but this update seemed to have fixed the issue!

Whenever you get EMPTY_FILELIST, it means MS has permanently removed this build and you have to search for the next available build.

If MS pulled it, they must have a reason.
I'll wait for next update. 🤞

Well, as others suggested, W.U. is downloading and installing the update when I switched to the insider R.P. channel.
I'll just restart now to complete the update. 😊🤷‍♂️

As mentioned in the blog, 26H1 is only meant for new machines with new processors, which I don't have.

Windows 11, version 26H1 is a scoped release​

  • Windows 11, version 26H1 will only be available on new devices with select new silicon as they come to market in early 2026.
  • Windows 11, version 26H1 is not offered as an in-place update from Windows 11, version 24H2 or 25H2 on existing devices.
  • There is no impact to devices already in market today.

At this time, devices with Qualcomm Snapdragon® X2 Series processors will come with Windows 11, version 26H1.
