2026-02 Preview Update (KB5077241) (26200.7922) is corrupt!

Question

I have Windows11 on an HP 17" laptop purchased in Dec 2011.
The following Windows update: 2026-02 Preview Update (KB5077241) (26200.7922)
would not install last week. I have a total tech membership with the Geek Squad through Best Buy and they couldn't get it to install when they remoted into my laptop, then the sound on my computer would not work, even with headphones. I now have several sound related files in the Windows Update window that cannot install (install error), even though I had 2 more Geek Squad techs try his best to install them, all had install errors. I then called HP and paid for a software service subscription since my laptop is out of warranty. They remoted into my laptop and did their best to get the sound driver files to install but to no avail. So now I have no sound on my computer and the only thing left to do is a Windows Restore. I am very upset about this since this will delete any apps not included with Windows and I cannot do that due at this time. I thought you should know that the above-mentioned Windows Update file seems to be the culprit for corrupting my sound driver and associated files (list attached). I want to let Microsoft know what damage this Preview Update files has done to my laptop.

Answer 1

The described behavior matches known cases where Windows updates or preview builds expose incompatibilities with audio drivers rather than permanently “corrupting” the hardware. In similar situations, resolution has come from correcting the audio driver stack rather than performing a full Windows reset.

Based on the context, there are two likely contributing factors:

1. Audio driver incompatibility after an update
   • Windows 11 feature or preview updates can surface issues with OEM audio drivers (for example, Realtek or vendor‑bundled audio enhancement software).
   • A documented case shows that after a Windows 11 update, audio began producing pops/clicks until the Realtek driver was rolled back or replaced by the in‑box “High Definition Audio Device” driver. Once the OEM driver was removed and the generic Microsoft driver installed automatically, audio functionality returned to normal.
   • Another documented case shows that when Windows reports “no audio device is installed,” the fix is to ensure a valid audio device/driver is present in Device Manager, install or roll back the correct driver from the PC manufacturer, and then run the built‑in Playing Audio troubleshooter.
2. Known Windows 11 audio compatibility holds
   • Windows 11 24H2 has had compatibility holds placed on certain devices when specific audio components are known to malfunction after an update (for example, devices using Dirac Audio with cridspapo.dll, or systems with specific Intel Smart Sound Technology driver versions).
   • In those cases, Microsoft blocks or delays the update to prevent exactly the type of audio failure described. Where an update has already been applied, the documented resolution is to update the affected audio/BIOS components (for example, updating Intel Smart Sound Technology drivers to a fixed version, or installing a critical BIOS update from the OEM) and then re‑check Windows Update.

Given the situation and the constraints (needing to avoid a full Windows Restore), the supported remediation path from the available information is:

1. Check and repair audio drivers via Device Manager
   • Open Device Manager and verify that an audio device is present and not flagged with an error.
   • If an OEM driver (for example, Realtek) is present and audio is not working, either:
     • Update it to the latest version from HP’s support site for the specific laptop model, or
     • If the latest version is already installed and still failing, uninstall the OEM audio device and driver package, then restart so Windows can install the in‑box “High Definition Audio Device” driver. A similar approach resolved post‑update audio popping for another Windows 11 user.
2. Run the Playing Audio troubleshooter
   • From Settings > System > Troubleshoot > Other troubleshooters, run Playing Audio.
   • This is the recommended next step when Windows reports that no audio device is installed or when audio fails after driver changes.
3. Check for and apply OEM/firmware updates
   • For devices where Microsoft has identified audio‑related compatibility issues, the fix has been delivered via OEM updates (for example, critical BIOS updates from ASUS, or updated Intel Smart Sound Technology drivers).
   • On the HP laptop, check HP Support Assistant or HP’s driver/firmware page for the exact model and install any audio, chipset, or BIOS updates marked as critical or recommended for Windows 11.
4. Use Windows Update after driver/firmware correction
   • Once audio drivers and any OEM firmware are corrected, use Settings > Windows Update > Check for updates to let Windows re‑evaluate the system.
   • Where Microsoft has applied safeguard holds for audio issues, those holds are lifted after the required driver/BIOS updates are installed, and updates then proceed normally.

To report the impact of the specific preview update to Microsoft, the most effective channels are:

• Using the built‑in Feedback Hub app on Windows to file a bug under Windows Update and Audio and sound, including the KB number, error messages, and a description of the lost audio functionality.
• Ensuring diagnostic data is allowed so the update failure logs and driver state can be analyzed.

This approach focuses on restoring audio without a full Windows reset and aligns with how similar Windows 11 audio issues have been resolved and how Microsoft tracks and mitigates update‑related driver regressions.
