Windows 10 update KB4048955 (build 16299.64) releases

Windows 10 Fall Creators Update gets quality update to fix Microsoft Edge, black screen, USB devices, and many other problems.

Microsoft is releasing update KB4048955, which is the first quality update that rolls out after the Windows 10 Fall Creators Update (version 1709) officially became available for PCs on October 17.

KB4048955 bumps the version number of Windows 10 to build 16299.64, and while it doesn’t deliver new features, it brings a small set of fixes to address a black screen problem, issues with Mixed Reality Portal, problems with USB devices, and a bunch of security patches.

Alongside the latest quality update for version 1709, Windows 10 version 1703 is getting update KB4048954 to address a long list of problems with the Creators Update.

Machines that lack network connectivity or have already encountered this issue should follow the steps in the Microsoft Answers thread “Missing apps after installing Windows 10 Fall Creators Update”.
