Your Windows 11 PC uploads your update files by default, but one setting controls where they go
It might be sharing your update files with strangers on the internet
Windows 11 has a feature called Delivery Optimization that allows PCs to share update files with each other, in addition to downloading them from Microsoft's servers. This is designed to make updates faster and more efficient. According to XDA Developers, this feature is enabled by default.
Some Windows 11 users have experienced issues with their desktop backgrounds after installing an update. The Register and The Register Science report that the August update preview caused some Windows 11 24H2 and 25H2 desktops to display a default black background, instead of the user's preferred setting. Microsoft has confirmed the issue and is working on a fix.
Affected users are unable to restore their customized settings, including slideshow settings and contrast themes, until a future Windows update resolves the issue. The problem prevents the correct loading of settings, causing the default black background to be used instead.
