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

The brand new cumulative update is KB4577069, and it boosts the OS build number to 17763.1490. It may be installed on the next systems:

Windows 10 version 1809
Windows Server version 1809
Windows Server 2019

Since it's an optional cumulative update, it's called a preview release, therefore it includes all the changes that might be part of the next updates shipping on the October 2020 Patch Tuesday.

There are several important alterations in this update, and one of these is the introduction of the warning in Ie that tells users the support for Flash Player is coming to a finish. 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 could be published after this date.

In addition, this update cuts down on the probability of missing fonts, whilst introducing fixes for Microsoft Office applications. Those who are using Microsoft Edge Legacy are also obtaining a welcome patch.

"Addresses an issue that might create the error "0x80704006. Hmmmm?-can't reach this page" when using Microsoft Edge Legacy. This issue is the place you attempt to reach websites on non-standard ports. Any website that utilizes a port listed in the Fetch Standard specification under bad ports or port blocking may cause this issue," Microsoft explains within the changelog, which you'll take a look at in full in the box following the jump.

There's also improvements for enterprises, including changes for group policies.

"Addresses a problem with setting the "Restrict delegation of credentials to remote servers" Group Policy using 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 can just use "Require Restricted Admin" when the server doesn't support ??Require Remote Credential Guard,'" the organization says.

Worthwhile to learn is the fact 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 the majority of us to work from home, the organization decided to push back the EOL simply to make certain IT admins have plenty of time to prepare for that change.

So at this time, the target date for Windows 10 version 1809 to be retired is November.

"We have been evaluating the public health situation and comprehend the impact this really is wearing a number of our customers. To help ease a few of the burdens clients are facing, we will 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 ultimate security update of these editions of Windows 10, version 1809 will be released on November 10, 2020 instead of May 12, 2020," Microsoft explains.

At this time, the most recent form of Windows 10 is 2004, or even the May 2020 Update, however the software giant will quickly start the rollout of a new feature update called October 2020 Update and internally referred to as version 20H2. The final build was already shipped to testers, and the public rollout would start with seekers, using the update thus becoming available for people who manually look for updates in Windows Update.
