According to the official changelog, “Windows 11 Insider Preview Quality Update (29591)” introduces various significant changes for Windows Update, rolls out the new Shared Audio feature, and pushes Storage settings improvements.
As part of build 28020.2134 (Experimental experience for version 26H1), the company is rolling out with the same Windows Update improvements as the Feature Platforms version and Simple Service Discovery Protocol (SSDP) changes.
Windows 11 build 29591
In the Experimental experience for Feature Platforms, the company is rolling out the ability to skip updates during the initial setup.
You can now extend the update pause indefinitely through the Windows Update settings.
In addition, the company is updating the Power menu options to always shut down or restart independently of updates, and there are more insights about updates.
Shared Audio
Windows 11 is also introducing a new “Shared Audio” feature that allows two people to listen to the same audio from a single computer simultaneously.
The feature uses Bluetooth LE Audio broadcast technology to stream audio to two compatible Bluetooth devices at once, making it easier to share music, movies, or other media without speakers.
Users can enable the feature from the Quick Settings panel by selecting “Shared Audio,” choosing two supported paired devices, and starting the audio session.
There’s also a new Taskbar indicator that appears whenever audio sharing is active. This visual cue makes it clear that your sound is being shared and provides one-click access to the sharing settings.
Storage changes
Microsoft is updating the Storage settings experience on Windows 11 to reduce unnecessary User Account Control prompts. Opening Settings > System > Storage will no longer immediately trigger a UAC dialog. Instead, the prompt now only appears when accessing the Temporary files section.
Windows 11 build 28020.2134
As part of the Windows 11 build 28020.2134, Microsoft rolls out general improvements and fixes to improve the overall experience.
In the Experimental experience for version 26H1, the company is rolling out the ability to skip updates during the initial setup.
You can now extend the update pause indefinitely through the Windows Update settings.
Furthermore, Microsoft is updating the Power menu options to always shut down or restart independently of updates, and there are more insights about updates.
In addition, this preview improves the reliability of Simple Service Discovery Protocol (SSDP) notifications to reduce instances where the service may become unresponsive.
Finally, in this preview, Microsoft notes a known issue that resetting a device may get stuck in “Reset this PC.”
Other details
It’s important to clarify that Windows 11 26H1 is not a feature update for existing devices. The software giant has explicitly confirmed that version 26H1 is not an upgrade path for computers running Windows 11 25H2 or any earlier release.
This release is designed exclusively for new ARM64 hardware and will ship only on next-generation computers, starting with devices powered by Snapdragon X2 Plus, Elite, and Extreme processors. Systems based on Intel or AMD platforms will never receive Windows 11 26H1 through Windows Update or any other supported upgrade channel.
