How to fix issue downloading Windows 11, version 25H2 update

My computer failed to update to Windows 11, version 25H2 yesterday night. Now, the computer's speakers are not working and the error message says there are "No output devices found" and "No input devices found." The troubleshooter tried to fix the problem automatically and told me to restart, but this did not fix the issue. I then noticed that the computer needed an update, but the update failed to download and said I was not connected to the internet despite the fact that the computer is currently connected to the internet (and when running the network and internet troubleshooter, it says that I am connected). The update troubleshooter said it was unable to resolve my problem and was unable to connect me to the Windows support chat. Please help!!

    To address the issue with downloading the Windows 11, version 25H2 update and the audio device errors, you can try the following steps:

    1. Check Internet Connection: Even if it shows you are connected, try disconnecting and reconnecting to your network. You can also restart your router.
    2. Run Windows Update Troubleshooter: Since the troubleshooter already ran, ensure that you have the latest version of the troubleshooter. You can access it through Settings > Update & Security > Troubleshoot > Additional troubleshooters > Windows Update.
    3. Check Device Manager for Audio Devices: Go to Device Manager (right-click on the Start button and select Device Manager). Look under "Sound, video and game controllers" to see if your audio devices are listed. If they are not, or if there is a yellow exclamation mark, you may need to update or reinstall the drivers.
    4. Install Pending Updates: If you can access the Windows Update settings, check for any pending updates and install them. Sometimes, installing the latest updates can resolve connectivity and device issues.
    5. Use the Feedback Hub: If the issue persists, consider reporting it through the Feedback Hub app. This can help Microsoft address the problem in future updates.
    6. Known Issues and Resolutions: Keep an eye on the Windows release health status for any known issues related to the 25H2 update, as there may be specific fixes or workarounds provided by Microsoft.

    If these steps do not resolve your issue, you may need to seek further assistance from Microsoft Support or the Microsoft Support Community for more tailored help.

    Hi,

    Your failed Windows 11 25H2 update likely caused two issues:

    Audio drivers were removed or disabled during rollback, so Windows can’t detect any output/input devices.

    Windows Update components got corrupted, making the system think it’s offline even though your network works.

     

    Fixing this means:

    Reinstall or update your audio drivers via Device Manager or your PC manufacturer’s site.

    Reset Windows Update components clear cache and restart services or run an in-place upgrade using the official ISO if updates still fail.

     

    Let me know how it goes, Happy to help!
