Here's what's fixed, improved, and still broken in Windows 10 build 18237

Microsoft released Windows 10 Insider Preview build 18237 to the Skip Ahead subset of the Fast ring today. There aren't a lot of new features - mainly it's just that the sign-in screen has Acrylic now - but there are a bunch of fixes, improvements, and known issues.

Here's what's fixed and improved in Windows 10 build 18237:

We fixed an issue where Task Manager couldn’t be resized in the previous flight.

We fixed and issue resulting in Settings crashing when navigating to Accounts > Sign-in in the previous flight.

We fixed an issue resulting in reduced Action Center reliability in recent flights.

We fixed an issue where if you opened one of the taskbar flyouts (like network or volume), and then quickly tried to open another, it wouldn’t work.

We fixed an issue for people with multiple monitors where if the Open or Save Dialog was moved between monitors some elements might become unexpectedly tiny.

We fixed an issue resulting in certain apps crashing recently when setting focus to the in-app search box.

We fixed an issue resulting in certain games, like League of Legends, not launching/connecting properly in recent flights.

We fixed an issue where clicking on web links in PWAs such as Twitter didn’t open the browser.

We fixed an issue resulting in certain PWAs not rendering correctly after the app had been suspended then resumed.

We fixed an issue where pasting multi-line text into certain websites using Microsoft Edge might add unexpected empty lines between each line.

We fixed a crash in recent flights when using the pen to ink in Microsoft Edge’s web notes.

We fixed a high hitting Task Manager crash in recent flights.

We fixed an issue resulting in Settings crashing for Insiders with multiple monitors when changing various options under Display Settings in the last few flights.

We fixed a crash when clicking the Verify link on the Accounts Settings page in recent flights.

We’ve added a new group policy for preventing the use of security questions for local accounts. This can be found under Computer Configuration > Administrative Templates > Windows Components > Credential User Interface.

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”.

Here are the 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.

There's also one known issue 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.

Keep in mind that 19H1 is still very early on in development, so these known issues might not accurately describe the problems that you might end up having. Known issues could also be added to the notes over time.

To install today's build, go to Settings -> Update & security -> Windows Update -> Check for update. If you're not on Skip Ahead yet, you can't sign up as there's limited availability. Luckily, these builds will arrive in the Fast ring soon enough.
