Improvements
This security update includes quality improvements. Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.

• [Cluster stability] Fixed: Many servers within the same cluster suddenly shut down. The network is less available, and latency rises.
• [Task Manager] Fixed: The CPU index number might be wrong when you set process affinity. This occurs on servers that have two or more non-uniform memory access (NUMA) nodes.
• [GB18030-2022] This update adds support for this amendment.
• [Memory leak] Fixed: Leaks occur when predictive input ideas show.
• [Windows Kernel Vulnerable Driver Blocklist file (DriverSiPolicy.p7b)] This update adds to the list of drivers that are at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.
• [Virtual machine (VM) storage pool] Fixed: Some operations that rely on a storage pool stop working. This occurs because the VM cannot reclaim disk space to do things, like load balancing.​​​​​​​
• [USB cameras] Fixed: Your device does not recognize the camera is on. This issue occurs after you install the January 2025 security update.
• Digital/Analog converter (DAC)] Fixed: You might experience issues with USB audio devices. This is more likely when you use a DAC audio driver based on USB 1.0. USB audio devices might stop working, which stops playback.
• [USB audio device drivers] Fixed: The code 10 error message, “This device cannot start” appears. This occurs when you connect to certain external audio management devices. ​​​​​​​
