Microsoft has quietly released the cumulative update KB4039396 for PC users running the Windows 10 Anniversary Update. This new quality update bumps the build number to 14393.1670, and it fixes the known issues that were present in the cumulative update build 14393.1613 released two weeks ago. One of these issues caused the Update History to not list previously installed updates, and another one could led WSUS servers to exhibit increased CPU, memory, and network utilization when scanning for updates after installing the last build.
All these issues are now fixed, and you can find the detailed changelog below:
- Addressed issue where Update History and hidden updates are lost and a full scan for updates happens after installing OS Updates 14393.1532 through 14393.1613, including KB4034658. Installing this update will not restore past update history or hidden updates for users who have already installed the listed updates. However, this current update will address this issue for users who have not yet installed them.
- Addressed issue with WSUS update metadata processing that can cause some clients to time out with a 0x8024401c error.
Microsoft says that the KB4039396 patch has no known issues, so there is no reason to delay the installation. As usual, you can download this latest cumulative update by checking Windows Update in the Windows 10 Settings app.
