The recent release of Windows 11 KB5050009 has unfortunately turned into a troublesome update for many users, including myself. After installing this year’s first update for Windows 11 24H2, I noticed that my Galaxy Buds 2 Pro were rendered completely non-functional. Despite efforts to repair the connection, nothing seemed to work until I uninstalled the update—fixing the issue instantly.
Problems attributed to KB5050009 seem to extend beyond just Windows 11 24H2, as reports indicate that KB5050021 has caused similar problems. Users running Windows 11 23H2 have specifically mentioned issues with USB DAC ports, leading to total headphone failures.
This situation is not solely isolated to Windows 11, either, with some Windows 10 users reporting comparable issues. It begs the question—should we prepare for a comprehensive article addressing these concerns? I’ve reached out to Microsoft and will provide further details once I have a response from them regarding these faults. However, one thing is clear: both USB DAC headphones are dysfunctional following KB5050009 and KB5050021 installations.
Bluetooth Connectivity Problems
As highlighted earlier, after installing the Windows 11 24H2 KB5050009 update, my Bluetooth headphones completely stopped functioning.
After the update, while my Bluetooth headphones connected, there was no sound transmission. This rendered watching anything on YouTube impossible, resulting in video buffering or audio render errors.
I attempted to unpair and reconnect the headphones, and even resetting the Bluetooth settings was fruitless. This pointed to significant issues in how Windows 11 KB5050009 is managing Bluetooth audio devices.
Fortunately, the solution was straightforward. By navigating to Settings > Windows Update > Update history and uninstalling the patch, my Bluetooth headphones regained their functionality.
This case illustrates the shortcomings of Windows 11 KB5050009. Rest assured, I only utilize official Microsoft applications and drivers, eliminating the possibility of conflicts due to third-party software. Other users have reported experiencing similar issues, highlighting a broader problem that extends even to those not using Bluetooth devices.
Webcam Detection Challenges
Adding to the frustrating list, I found that my HP Spectre’s integrated camera became undetectable post-update.
Even after uninstalling the update, my camera still returned a “Camera not detected”error. It was only after a complete reinstallation of Windows 11 that functionality was restored—an arduous process indeed.
It appears I’m far from alone in facing these issues. Reports from users on the Feedback Hub indicate that models like the Dell 4K monitor with an integrated webcam (such as P3424WEB and P2424HEB) are displaying “Device cannot start”errors.
Furthermore, some users have encountered similar issues with webcams like Insta360 Link, which Windows inexplicably recognizes as USB audio devices.
USB DAC Failures
Another alarming observation among users is the sudden dysfunction of headphones connected through USB DAC post-Windows 11 KB5050009 installation on 24H2 and KB5050021 on 23H2.
A community user stated, “My headphones connected through a USB DAC have suddenly ceased to function. I’ve confirmed that the DAC still operates correctly with a different laptop. Uninstalling KB5050021 resolved the issue.” This suggests that the reinstallation of the update has been a recurring nuisance, prompting users to pause Windows Updates altogether—far from ideal.
Symptoms reported include the driver indicating an error stating, “Insufficient system resources exist to complete the API.” Products affected span popular models, like the JDS Labs ODAC, Fiio E17K USB DAC, FX-Audio DAC-X6, HyperX USB headsets, and Denon CEOL Carino.
Other General Bugs Post-Update
Sadly, the catalog of problems extends even further. Following the Windows 11 24H2 update, users have noted that the Alt+Tab function occasionally freezes or crashes during gameplay sessions. Numerous titles, such as Fortnite and Assassin’s Creed, have been affected, with entire desktops or Explorer.exe ceasing to function.
Additionally, frequent reports document installation issues with KB5050009, where users face incessant prompts to restart or encounter error code 0x80070005.
Lastly, since the update, many users have also reported that Smart App Control is mistakenly blocking numerous applications, including essential WSL components.
The only remedy currently available for most of these problems is to uninstall the problem update and pause further updates while we await a resolution from Microsoft based on user feedback.
How to Address Windows 11 24H2 January 2025 Update Challenges?
The most effective workaround for rectifying these issues is straightforward: uninstall the KB5050009 update, pause future Windows Updates, and keep an eye out for further developments from Microsoft.
