KB4482887 for Windows 10 version 1809

Microsoft released the cumulative update KB4482887 for Windows 10 version 1809 yesterday. The update brings the build of that particular version of Windows 10 to 17763.348.

Microsoft appears to test updates for the latest version of Windows 10 in the Release Preview ring before it pushes them out using Windows Update and other means. The practice delays the release of the update; all other supported versions of Windows 10 received updates in mid-February 2019 already.

KB4482887 is available on Windows Update already; devices configured to download and install updates automatically will pick up the update eventually. You may run a manual check for updates to speed up the process, or download the new cumulative update for Windows 10 from the Microsoft Download Catalog site instead.

Issues in KB4482887

Microsoft lists two issues on the support page.

1. Users may receive "Error 1309" when installing or uninstalling certain MSI or MSP files. Microsoft asks users to ignore the error.
2. Internet Explorer 11 authentication issues when two or more people use the same user account for multiple, concurrent login sessions on the same Windows Server machine, including Remote Desktop Protocol (RDP) and Terminal Server logons.
