KB4093105 for Windows 10 version 1709

Microsoft published KB4093105, a new cumulative update for Windows 10 version 1709, the Fall Creators Update, some hours ago. The non-security update is distributed via Windows Update and other updating services, and available as a standalone download from the Microsoft Update Catalog website.

The update brings the build number of the operating system to 16299.402. Microsoft released the cumulative updates KB4093120 and KB4093117 for Windows 10 version 1703 and 1607 last week, and KB4093105 shares several of the fixes with these earlier releases.

KB4093105 fixes issues in Microsoft Outlook, Windows Hello, File Explorer, BitLocker, Microsoft Edge and other programs and core operating system features.

Note: Windows Update failed to pick up the new update on a Windows 10 Pro machine. It returned KB4093112 instead which Microsoft released on the April 2018 Patch Tuesday; that update was installed on the machine already, however. Manual download from the Microsoft Update Catalog site and installation worked, however.


The list of issues that Microsoft fixed in the new update is quite large. You can check it out on the official release history page on the Microsoft website, or read the summary (of all fixes) below.
  • Fixed an issue where the deprovisioning of apps using remove-AppXProvisionedPackages-Online did not work properly as apps returned after upgrades.
