Okay, so apparently Windows 10 October 2018 Update has already become an old news as Microsoft is dropping new Windows 10 2019 Preview Builds. Windows 10 Insider Preview Build 18252 is available to Windows Insiders in the Fast ring and Skip Ahead. This is the first build from the Windows 10 2019 being rolled out to the Fast ring, so things are going to get exciting for this particular ring.

"Going forward, Insiders in the Fast ring and in Skip Ahead will receive the same 19H1 Insider Preview builds at the same time," Microsoft wrote. "As is normal with builds early in the development cycle, builds may contain bugs that might be painful for some. If this makes you uncomfortable, you may want to consider switching to the Slow ring."

If you were slow to switch to the stable ring and this Preview Build has already been installed then you can roll back and then switch the rings.

Back to today's release, here is everything that's new and fixed with Windows 10 2019 18252:

Network improvements

Enhanced settings for Ethernet: We’ve heard your feedback, and you can now use the Settings app to configure advanced Ethernet IP settings. We have added support for configuring a static IP address as well as setting a preferred DNS server. These settings were previously accessed within Control Panel, but you will now find them on the connection properties page under IP settings.

New icon for disconnected internet: First seen on Always Connected PCs, as some keen eye’d Insiders noticed, we have brought the disconnected internet icon to all devices running Windows 10. This single icon appears when there is no internet connection detected, and replaces the individual disconnected icons for Cellular, Wi-Fi, and Ethernet. This new icon should help you quickly identify network problems so that you can take action to resolve them.

Ebrima font addition with ADLaM support

The Windows team is pleased to announce you can now read your ADLaM documents and webpages with the Windows Ebrima font!

ADLaMis a writing system for Pular/Fulfulde, the language of the Fulani people, predominantly residing in west Africa. In the early 1990s, two young teenager brothers, Abdoulaye and Ibrahima Barry, created this writing system. Their work became “Bindi Pulaar” and eventually “ADLaM,” ADLaM is enabling literacy and growing in use for commerce, education, and publishing across western Africa. It was added to Unicode in Unicode 9.0.

The Ebrima font also supports other African writings systems N’ko, Tifinagh, Vai and Osmanya – here’s a sample of what the font looks like:

Windows 10 2019 Build 18252 general changes, improvements, and fixes

• We fixed the issue causing Task Manager to report inaccurate CPU usage.
• We fixed the issue where the arrows to expand “Background processes” in Task Manager blink constantly and weirdly.
• We added a microphone icon in the system tray which appears when your microphone is in use.
• Pressing F4 when in Registry Editor will now place the caret at the end of the address bar, expanding the autocomplete dropdown.
• We fixed an issue where when using dark mode File Explorer’s context menu had an unexpectedly thick white border in recent builds.
• We fixed an issue resulting in the advanced startup pages not rendering text correctly (showing square boxes instead) in certain languages, like Thai.
• We fixed the issue causing Narrator to crash when reading by line in a Command Prompt.
• We fixed the issue where Narrator did not read out the Windows Security application name in Shell Notification area (Systray) and only read the recommended actions.
• The corresponding Ethernet adapter name will now be listed in the sidebar under the “Ethernet” header so you can easily differentiate Ethernet entries at a glace if there’s more than one.
• In RS5 we introduced extra pages to the Emoji Panel when using it in Chinese (Simplified), and based on your feedback we’re looking to expand these to more languages. After upgrading to today’s build, some Insiders may see them – more details coming later.
• We fixed an issue resulting in Windows Hello not working on the login screen in the previous build (instead of logging in it would prompt you to enter a pin).
