You’ve probably experienced it: you install a Windows update hoping for improvements, only to find something else breaks. While frustrating, these situations happen more often than we’d like—but the upside is that Microsoft usually moves fast to identify and fix them.
That was the case in August 2025, when a Windows security patch caused serious problems for streaming applications. The bug affected both Windows 10 and Windows 11, impacting content creators, gamers, and businesses relying on live streaming.
At TecnetOne, we explain what happened, how Microsoft resolved it, and how you can protect your systems from similar incidents.
The Bug That Disrupted Streamers and Businesses
The issue stemmed from updates KB5063878 and KB5063709 (for Windows 11 24H2 and Windows 10 versions 21H2 and 22H2).
After installation, users began experiencing:
- Major delays during live streams
- Choppy audio and video
- Persistent stuttering in key tools like OBS Studio and NDI Tools
For content creators and companies that depend on broadcasting, this was more than a nuisance—it was a threat to performance, reputation, and even revenue.
Microsoft Acknowledges the Problem
At first, it seemed like an isolated issue. But soon, forums, social media, and support platforms were flooded with complaints. The NDI team itself confirmed that the update was interfering with their apps’ data flow.
After investigating, Microsoft publicly acknowledged the bug on its official blog, confirming that the patch could disrupt audio and video transmission, especially when using NDI protocols. They didn’t stop there—they released a fix shortly after.

September Patch: The Permanent Fix
On September 9, 2025, Microsoft rolled out updates KB5065426 and KB5065429, which address the issue.
Microsoft’s advice: install these patches as soon as possible.
Besides resolving the streaming problems, the updates also:
- Fixed a bug triggering unwanted User Account Control (UAC) prompts
- Resolved app installation issues for non-admin user accounts
Temporary Workaround from NDI
If you couldn’t apply the patch immediately, NDI offered a workaround: switching the NDI receive mode to use UDP or TCP instead of RUDP.
While not a perfect fix, this approach helped reduce stuttering and lag, offering at least a temporary level of stability.
The Ongoing Dilemma: Updates That Break Things
This isn’t the first time, and likely won’t be the last. Windows has a reputation for updates that sometimes do more harm than good.
Why? Because Windows supports an enormous ecosystem: millions of hardware configurations, thousands of driver versions, and countless apps. It’s no surprise that a security patch meant to fix a vulnerability might unintentionally disrupt something else.
Still, what matters most is Microsoft’s response speed—and in this case, it was quick and decisive.
Real-World Consequences for Users and Businesses
This issue wasn’t just a gamer or streamer problem. It affected:
- Companies conducting live corporate broadcasts
- Media outlets using OBS or NDI for live coverage
- Educational institutions streaming classes or lectures
- Independent professionals who rely on high-quality streaming for income
When a stream stutters or the audio fails, it’s not just a technical glitch—it erodes audience trust and can hurt business outcomes.

Best Practices for Dealing with Problematic Updates
At TecnetOne, we always recommend a proactive strategy for dealing with updates. Here’s what we advise:
- Avoid installing critical updates immediately on production machines—test them first
- Create backups and restore points before applying updates
- Monitor Microsoft’s official channels for known issues and fixes
- Keep an eye on forums and social media for early signs of trouble
- Have a rollback plan in case something breaks: know how to uninstall updates or apply temporary workarounds
The Upside: Microsoft Is Listening
As frustrating as these bugs can be, they also show something encouraging: Microsoft listens. They not only acknowledge major problems quickly but act fast to fix them—and sometimes provide interim solutions, too.
This time, Microsoft didn’t just fix the streaming issue. They also took the opportunity to enhance system security and usability.
Final Thoughts
Faulty updates are an inevitable risk in complex software environments. But what really counts is the response. Microsoft proved it can move swiftly and effectively to minimize disruption.
For you—as an individual or a business—the lesson is clear:
- Stay informed
- Install official security patches
- Never leave your cybersecurity to chance
At TecnetOne, we believe the key to digital resilience is prevention, continuous monitoring, and contingency planning. Because when your operating system fails, your infrastructure shouldn’t.
