Microsoft releases Windows 10 builds 16299.64, 15063.728; here's what's new

Today is Patch Tuesday, which means that it's that time of the month when Microsoft updates all versions of Windows 10. In total, there are six separate cumulative updates for the OS, as phones on version 1709 are on a different branch than PCs now.

PCs on the Fall Creators Update will see KB4048955, or build 16299.64. You can manually download it here, and it includes the following fixes:

  • Addressed issue that causes the Mixed Reality Portal to stop responding on launch.

  • Addressed issue that causes a black screen to appear when you switch between windowed and full-screen modes when playing some Microsoft DirectX games.

  • Addressed a compatibility issue that occurs when you play back a Game DVR PC recording using Android or iOS devices.

  • Addressed issue where the functional keys stop working on Microsoft Designer Keyboards.

  • Addressed issue to ensure that certain USB devices and head-mounted displays (HMD) are enumerated properly after the system wakes up from Connected Standby.

  • Addressed issue where the virtual smart card doesn't assess the Trusted Platform Module (TPM) vulnerability correctly.

  • Addressed issue where Get-StorageJob returns nothing when there are storage jobs running on the machine.

  • Addressed issue where applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) fail when creating or opening Microsoft Excel .xls files. The error message is: “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".

  • Addressed issue where application tiles are missing from the Start menu. Additionally, applications that the Store app show as installed don't appear on the application list of the Start menu. Computers that have Internet connectivity and upgrade on or after November 14, 2017 will receive this preventative solution and avoid this issue. 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”. Microsoft will release and document an additional solution in a future release.

  • Addressed issue where Microsoft Edge cannot create a WARP support process and appears to stop responding for up to 3 seconds during a wait timeout. During the timeout period, users cannot navigate or interact with the requested page.

  • Security updates to Microsoft Scripting Engine, Microsoft Edge, Microsoft Graphics Component, Windows kernel, Internet Explorer, and Windows Media Player.

Phones, on the other hand, will get KB4052314, or build 15254.12, and the changelog only says that it contains the improvements that are in KB4048954.

And of course, that brings us to KB4048954 for users of version 1703, which relates to builds 15063.726 and 15063.728. It's available for both PCs and phones; however, the only phones that should really need it are the Lumia 640 and 640 XL, as those were the ones that didn't get version 1709. You can manually download it here, and it contains the following fixes:

  • Addressed issue where applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) fail when creating or opening Microsoft Excel .xls files.
