Here's what's fixed, improved, and still broken in Windows 10 build 19546

Today, Microsoft released Windows 10 Insider Preview build 19546 to the Fast ring. It only includes one new feature, which is graphics mode for Windows Calculator.

As always though, there's a long list of fixes, improvements, and known issues to be aware of. Here's what got fixed and improved in build 19546:

  • We fixed an issue resulting in Timeline not showing any activities.
  • We fixed an issue resulting in Outlook search not working for some.
  • We fixed an issue significantly impacting Task View reliability for some.
  • We fixed an issue where pressing Spatial Sound -> Off in the sound menu caused Explorer.exe to crash.

Here are the known issues:

  • BattlEye and Microsoft have found incompatibility issues due to changes in the operating system between some Insider Preview builds and certain versions of BattlEye anti-cheat software. To safeguard Insiders who might have these versions installed on their PC, we have applied a compatibility hold on these devices from being offered affected builds of Windows Insider Preview. See this article for details.
  • We are aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues. Users of legacy Microsoft Edge will not be affected.
  • The cloud recovery option for Reset this PC isn’t working on this build. Please use the local reinstall option when performing Reset this PC.
  • We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • We’re investigating reports that some Insiders are unable to update to newer builds with error 0x8007042b.
  • We’re looking into reports of certain external USB 3.0 drives not responding with Start Code 10 after they’re attached.
  • The Optimize Drives Control Panel is incorrectly reporting that optimization has never run on some devices. Optimization is completing successfully, even though it is not reflected in the UI.
  • The Documents section under Privacy has a broken icon (just a rectangle).
  • Remote Desktop Connection crashes when attempting to connect to multiple sessions.
  • Snipping isn’t working on secondary monitors.
  • The IME candidate window for East Asian IMEs (Simplified Chinese, Traditional Chinese, and the Japanese IME) may not open sometimes. We are investigating your reports. As a workaround if you encounter this, please change the focus to another application or editing area and back to the original and try again. Alternatively, you can go to Task Manager and end the “TextInputHost.exe” task from the Details tab, and it should work afterwards.

Obviously, some of the issues are more serious than others. The one about anti-cheat software has been there for over a year now, and it's not going away. Game developers have to update their games, rather than Microsoft updating Windows. Presumably, this will just be listed in the known issues forever.

One issue that might be more serious is certain USB 3.0 devices now working properly. Also, snipping not working on secondary monitors might break your work flow. As always, you should be aware of these things before installing a new build.

With the way that these things are, this is only a preview of Windows 10, not one that's tied to any specific release. Normally, we'd say that this is a preview of 20H2 or 21H1, but Microsoft doesn't want to be held accountable for saying that it will ship a feature in a certain release and then not doing so.
