New Issue Confirmed in Windows 10 Version 1809 Cumulative Update KB4489899 

Microsoft has recently acknowledged the fifth issue in Windows 10 cumulative update KB4489899 for version 1809 (October 2018 Update).

Microsoft has recently acknowledged the fifth issue in Windows 10 cumulative update KB4489899 for version 1809 (October 2018 Update).

KB4489899 was published as part of the Patch Tuesday cycle on March 12 and originally came with just two different known bugs.

According to the updated KB page, installing KB4489899 could break down the Preboot Execution Environment (PXE) on Windows 10. Microsoft explains the following:

“After installing this update, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension. This may cause the connection to the WDS server to terminate prematurely while downloading the image. This issue does not affect clients or devices that are not using Variable Window Extension.”A fix is on its wayWhile the company says it’s already working on a fix, which would be included in an upcoming release, Microsoft also recommended users to disable the Variable Window Extension on WDS server. There are several methods to do this, and you can check them in full on the update KB article.

There are no specifics as to when a fix could be published, but Microsoft is expected to release new cumulative updates for Windows 10 later this month. However, since no details were shared, I believe there are bigger chances for this bug to be resolved with the cumulative updates coming the next Patch Tuesday, which takes place on April 9.

The bug has also been confirmed in the other Windows 10 cumulative updates published this month, including in KB4489868 for Windows 10 version 1803 (April 2018 Update).

Needless to say, this bug won’t affect consumers, so if you’re a home user, you should check out the other known issues that have already been acknowledged in this month’s cumulative updates.
