On Friday night, Microsoft announced new unwanted side effects of the Windows updates for the August Patchday. The streaming of audio and video data may not work properly after installation.
In the Windows Release Health notes, Microsoft writes that "severe stuttering, lag and choppy audio and video" may occur when using the Network Device Interface (NDI) to stream audio and video. "The issue affects streaming apps, including Open Broadcast Software (OBS) and NDI tools, especially when 'Display Capture' is enabled on the source PC. The issue also exists in low bandwidth conditions," Microsoft's developers explain.
Temporary countermeasure recommended
Apparently, those affected can work around the problem by manually switching the "NDI Receive Mode" to use TCP or UDP instead of the default "RUDP". Microsoft refers to a separate website on the NDI domain with instructions to help with the implementation of this workaround. According to this, the NDI tools should be installed, and the "NDI Access Manager" app started from there. This allows the receive mode to be switched to "Single TCP" or "UDP". This is necessary for all affected computers. However, the alternative suggestion of uninstalling the Windows update is not recommended: The security update plugs security holes that attackers can abuse. According to Microsoft, the issue can occur under Windows 11 24H2, Windows 10 22H2 and Windows 10 21H2.

There were already several known side effects of Windows updates on Patchday in August; this month there was a significant increase. The installation of updates via WSUS could fail with an error code 0x80240069, for example. Microsoft was able to correct this on Tuesday, but other problems were already known. For example, resetting or restoring certain Windows versions after applying the security patches failed. An out-of-sequence update on Wednesday resolved the issue. However, Microsoft is still investigating another side effect that apparently paralyzes some SSDs when the August updates are installed.
