Known Issues in Windows 10 Cumulative Update KB4489899

Microsoft rolled out Windows 10 cumulative update KB4489899 for devices running version 1809 (October 2018 Update), and the company acknowledged three different issues.

First of all, update KB4489899 retains the web Explorer 11 that was discovered within the February 2019 cumulative update and which in turn causes authentication problems in the browser.

“This occurs when two or more people use the same user account for multiple, concurrent login sessions on a single Windows Server machine, including Remote Desktop Protocol (RDP) and Terminal Server logons,” Microsoft says, adding that a patch could be shipped within an upcoming release.

Then, the software giant states that some systems with multiple audio devices could experience sound issues after installing the update. The applications that could encounter such problems include Windows Media Player, Realtek HD Audio Manager, and Sound Blaster User interface. Microsoft says users can manually set a default audio device within their apps, like a fix ought to be released later this month.

“KB4489899 apparently installing correctly for everyone”

And finally, cumulative update KB4489899 also causes errors for several applications and also the Group Policy Editor.

“After installing this update, MSXML6 causes applications to stop responding if the exception was thrown during node operations, such as appendChild(), insertBefore(), and moveNode(),” Microsoft says. “Group Policy editor may also be affected when editing an organization Policy Object (GPO) which contains an organization Policy Preference for Internet Settings.”

In this case, the organization says a resolution could be included in a future update, but no ETA has been provided this time around.
