New optional update available for Windows 10 version 1809

Microsoft has released a new optional cumulative update for Windows 10 version 1809, and users can download it today from the Microsoft Update Catalog or by simply checking for updates manually on Windows Update.

The new cumulative update is KB4577069, and it increases the OS build number to 17763.1490. It can be installed on the following systems:  

  • Windows 10 version 1809
  • Windows Server version 1809
  • Windows Server 2019

Since it’s an optional cumulative update, it’s labeled as a preview release, so it includes all the changes that would be part of the next updates shipping on the October 2020 Patch Tuesday.

There are several important changes in this update, and one of them is the introduction of a warning in Internet Explorer that tells users the support for Adobe Flash Player is coming to an end. Flash Player would be retired in December, at which point Microsoft will abandon it for both Internet Explorer and Microsoft Edge. In other words, no new security updates would be published after this date.

In addition, this update reduces the likelihood of missing fonts, while also introducing fixes for Microsoft Office applications. Those who are using Microsoft Edge Legacy are also getting a welcome patch.

“Addresses an issue that might generate the error ”0x80704006. Hmmmm…can’t reach this page” when using Microsoft Edge Legacy. This issue occurs when you attempt to reach websites on non-standard ports. Any website that uses a port listed in the Fetch Standard specification under bad ports or port blocking might cause this issue,” Microsoft explains in the changelog, which you can check out in full in the box after the jump.

There are also improvements for enterprises, including changes for group policies.

“Addresses an issue with setting the “Restrict delegation of credentials to remote servers” Group Policy with the “Restrict Credential Delegation” mode on the RDP client. As a result, the Terminal Server service tries to use “Require Remote Credential Guard” mode first and will only use “Require Restricted Admin” if the server does not support ‘Require Remote Credential Guard,’” the company says.

Worth knowing is that Windows 10 version 1809 is approaching its end of support. Previously, Microsoft wanted to retire this release in May 2020, but due to the lockdown that happened globally and which forced most of us to work from home, the company decided to push back the EOL just to make sure IT admins have enough time to prepare for the change.

So right now, the target date for Windows 10 version 1809 to be retired is November.

“We have been evaluating the public health situation and understand the impact this is having on many of our customers. To help ease some of the burdens customers are facing, we are going to delay the scheduled end of service date for the Home, Pro, Pro Education, Pro for Workstations, and IoT Core editions of Windows 10, version 1809 to November 10, 2020. This means devices will receive monthly security updates only from May to November. The final security update for these editions of Windows 10, version 1809 will be released on November 10, 2020 instead of May 12, 2020,” Microsoft explains.

Right now, the most recent version of Windows 10 is 2004, or the May 2020 Update, but the software giant will soon start the rollout of a new feature update called October 2020 Update and internally referred to as version 20H2. The final build has already been shipped to testers, and the public rollout would begin with seekers, with the update thus becoming available for those who manually check for updates in Windows Update.
