KB4089848 for Windows 10 version 1709

KB4089848 is a new cumulative update for Windows 10 version 1709 (Fall Creators Update) that increases the version of the operating system to build 16299.334 after installation.

The update fixes issues in the Windows 10 Fall Creators Update and comes along with the dreaded "update failed to install" message even though that is not the case.

The support page on the Microsoft website lists key changes only which indicates that the update may include other changes that Microsoft did not list. That's a standard phrase, however, that Microsoft uses regularly in update descriptions.

Note: We suggest you back up the entire Windows 10 partition before you install any update on the system so that you may restore it to a previous version if you run into issues after installation of the update.

KB4089848 is distributed through Windows Update but it is also available as a standalone download on the Microsoft Update Catalog website. The Microsoft Update Catalog download has a size of 401 Megabytes for the 32-bit version and 735 Megabytes for the 64-bit version.

The Windows Update version should be considerably smaller.

1. Use Windows-I to open the Settings application.
2. Select Update & Security.
3. Activate the "check for updates" button to run a manual update check.
