[Graeme269]

Windows Insider Preview 10.0.25336.1010 fails to download. Gets to 8% then fails Download Error - 0xffff0000. I have tried the troubleshooting but still same result. Previous update 25330 also failed with the same error. I am currently running build 25314. Any help would be much appreciated.

As you know the insider build is under the testing and development.
I advise you to open start and search for feedback and open the Feedback Hub app and report this issue.

Hi, this is an old bug, you can check these steps:

“We couldn’t update system reserved partition” error installing Windows 10 - Microsoft Support

Downloading the ISO is the simplest solution (an in-place update should fix this)

Download Windows Insider Preview ISO (microsoft.com)
