Microsoft’s first Windows 11 patch of 2025 “is turning out to be a disaster,” as another raft of incompatibility issues and unintended consequences seems to have hit the first Windows 11 patch of 2025. Fortunately, there’s a fix.
As reported by the ever-reliable Windows Latest, “Windows 11 KB5050009 has a lot of issues, and it’s not just limited to Windows 11 24H2 because we’ve also seen reports where KB5050021 has similar or different issues.”
TechRadar goes even further. “It’s not a secret that Microsoft’s Windows 11 24H2 has been a massive problem for plenty of PC users, with bugs and functionality issues present across the board, which has more recently affected gamers — and now, it looks like a new set of issues have arrived to cause more frustrations.”
According to Windows Latest, this isn’t even just a Windows 11 problem — Windows 10 also has issues with its January fixes. For both versions of the OS, the bug that seems to be causing the most ire is headphone related. “The USB DAC fails to load. If you’re affected, you might run into ‘This device cannot start. (Code 10). Insufficient system resources exist to complete the API’.”
It seems that Bluetooth headsets also cut out for those users affected by the failed update. “After the update, Bluetooth headphones were still getting connected, but there was no audio. I was also unable to watch anything on YouTube because the video would buffer or fail with an audio render error.” There also seems to be an even more widespread issue with webcams failing to work after the update.
The buggy update issue has been something of a constant with this latest Windows release, and isn’t helping the drive to push reluctant Windows 10 users to upgrade. “The biggest problem,” says TechRadar, “is that it can be hard to diagnose some of the reported issues — there’s an abundance of different PC setups, with different applications installed which could be responsible for some bugs.”
There is a fix though. “The workaround for all these issues is to uninstall the update, pause Windows Update,” Windows Latest advises, “and wait for Microsoft to do something with your feedback report. There’s nothing more you can do.”
We’re approaching the home straight for Windows 11 to finally displace its older sibling before its end-of-life in October. Microsoft has offered a free upgrade path for users, but there is no sign yet of the widespread reluctance dissipating. And this won’t help. I have approached the company for any comments on these new problems.
