Today Microsoft released Windows 10 Insider Preview Build 18237 (19H1) to the Insiders on the Skip Ahead ring. This build adds a translucent Acrylic texture to the sign-in lock screen as well as fixes various issues and bugs. Also announced is the renaming of the Microsoft Apps Android application to "Your Phone Companion".

Build 18237 Insider Update

As always, if you are in the Skip Ahead ring you can update to this new build by checking for new updates.

Acrylic added to the sign-in screen background

Microsoft has added the Acrylic brush texture to the sign-in screen background. This adds a clean translucent texture that causes the background image to blur so that you can focus on the task at hand, which in this case is signing into Windows.

Microsoft Apps Android app rebranded as Your Phone Companion

To make it less confusing, Microsoft has renamed the Android "Microsoft Apps" app so that it now named "Your Phone Companion". This is being done to make it easier to understand that the Android app is a companion to the Your Phone feature in Windows 10.

"This week, we are bringing our apps closer together – Your Phone app on PC now links you to Your Phone Companion app on your Android phone," stated this build's release notes. "See the resemblance? Companions? Yea thought you’d like that! We heard your feedback on having both apps share a stronger name game. If you’ve previously installed Microsoft Apps on your Android phone, when the app auto-updates, you’ll see a fresh set of screens that maintain the mobile app’s visual connection to Your Phone app on PC. Loved the fact that the mobile app used to surface up other apps by the same maker, Microsoft? No fear, it’s still there. Tap on ‘Top Microsoft Apps’ to get 20 quick recommendations. Or click on the left menu button, and browse through mobile apps from Microsoft, organized by app categories."

We fixed an issue where the contents of the Apps & Features page wouldn’t load until the apps list was ready, resulting in the page appearing blank for a time.

We fixed an issue where the list on Settings of built-in phrases for the Pinyin IME was blank.

We fixed an issue in Narrator where activating Microsoft Edge history items would not work in Scan mode.

We made some improvements in Narrator Selection when moving forward in Microsoft Edge. Please try this out and use the Feedback hub app to let us know any issues you encounter.

We fixed an issue where Narrator would incorrectly report some standard combo boxes as “editable combo box” instead of “combo box”.

Known issues

Narrator sometimes does not read in the Settings app when you navigate using Tab and arrow keys. Try switching to Narrator Scan mode temporarily. And when you turn Scan mode off again, Narrator will now read when you navigate using Tab and arrows key. Alternatively, you can restart Narrator to work around this issue.

You may notice the background of notifications and the Action Center lose color and become transparent (with an acrylic effect). We’re aware that for notifications this can make them difficult to read and appreciate your patience as we work on a fix.

Known issues for Developers

If you install any of the recent builds from the Fast ring and switch to the Slow ring – optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

Update 8/12/18: Added information about Error 0x8007000e and heavy RAM usage during installation of Windows 10 Insider Preview Build 18237.
