New update shipped to Beta and Release Preview channels

Microsoft has released a new Windows 10 preview build for insiders enrolled in the Beta and Release preview channels of the testing program.

More specifically, Windows 10 build 19042.541 is available with the installation of cumulative update KB4577063, and it is a preview of Windows 10 version 20H2, or the October 2020 Update.

First and foremost, one of the most notable improvements concerns the Windows Subsystem for Linux, which now works correctly thanks to this update. Previously, users running Windows 10 October 2020 Update preview builds couldn’t launch WSL on their devices because the process failed with an “Element not found” error.

This update also introduces a warning for Internet Explorer 11 users that reminds support for Adobe Flash Player is coming to an end in December this year. In other words, if for some reason you still use Internet Explorer, you should see a notification at the top of the screen that tells you Flash Player is getting the ax.

Microsoft says it has also corrected a bug affecting Microsoft Edge IE mode and included fixes aimed at the Language Bar.

“We fixed an issue that, in some instances, prevents the Language Bar from appearing when the user signs in to a new session. This occurs even though the Language Bar is configured properly,” the company explains in the changelog that you can also check out in full in the box after the jump.

There’s also an important bugfix aimed at applications using the Windows API to check for an Internet connection. Microsoft says that these apps previously failed to launch, so now everything is supposed to work correctly after the installation of cumulative update KB4577063.

“We fixed an issue that might prevent applications from opening or cause other errors when applications use Windows APIs to check for internet connectivity and the network icon incorrectly displays “No internet access” in the notification area. This issue occurs if you use a group policy or local network configuration to disable active probing for the Network Connectivity Status Indicator (NCSI). This also occurs if active probing fails to use a proxy and passive probes fail to detect internet connectivity,” the company explains.

There are also important fixes for enterprises, as the new cumulative update resolves an issue hitting a Group Policy.

“We fixed an issue with setting the “Restrict delegation of credentials to remote servers” Group Policy with the “Restrict Credential Delegation” mode on the Remote Desktop Protocol (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,’” Microsoft notes.

Windows 10 October 2020 Update has already been finalized, and users in the Beta and Release Preview channels are currently running the final build of this feature update. Microsoft continues to focus on improvements and bug fixes, and these are all distributed to devices using cumulative updates like the one we’re talking about today.

Microsoft hasn’t announced a release date as to when the October 2020 Update would begin the rollout to production devices, but if everything runs according to the plan, it shouldn’t take more than a few weeks before this is announced. As per Microsoft’s typical release calendar, the fall feature update for Windows 10 is finalized in September, while the rollout to the first wave of devices kicks off in October or November. Judging from its name, the October 2020 Update should land on our computers beginning next month.
