Here's what's fixed, improved, and still broken in Windows 10 build 17046

Microsoft released Windows 10 build 17046 to Insiders on the Fast ring today, adding a range of minor new features, such as the ability to add multiple emojis at once through the Emoji Panel. It's the last build before the Insider team heads off for the holiday weekend.

But as always, there are a bunch of fixes, improvements, and known issues listed in the release notes. Here's what got fixed and improved:

• We’ve added settings that let you view and manage your activity history, which Cortana uses to let you pick up where you left off. Find these settings in Settings > Privacy > Activity history.

• We fixed an issue where the Properties dialog for This PC in File Explorer wasn’t working in the last two builds.

• We fixed an issue resulting in Insiders with certain third party antiviruses and OneDrive Files on Demand enabled seeing an error in recent builds citing “OneDrive cannot connect to Windows”.

• We fixed an issue that could result in delays during logoff and shutdown when a UWP app was open and in suspended state.

• We fixed a community reported issue where display colors became distorted after upgrading on some TV’s and monitors that incorrectly advertised support for 10/12 bit wire formats.

• We fixed an issue from the previous flight that could cause heavily-threaded DirectX 12 apps to crash on launch after the first launch.

• We’ve adjusted the application of acrylic in the touch keyboard to better align with the fluent design standards.

• We fixed an issue where keys might remain highlighted when typing on the wide touch keyboard layout.

• We fixed an issue where keys might be dropped when typing with the Chinese (Simplified) touch keyboard.

• We fixed an issue where when writing a long sentence in the handwriting panel it might scroll while your pen was writing, resulting in an ink stroke across the panel.

• We fixed an issue resulting in the hardware keyboard text suggestions potentially not working until the touch keyboard had been launched once.

• We fixed an issue resulting in the mouse noticeably flickering between + and the mouse pointer icon when moving across cells in Excel 2016.

• We fixed an issue resulting in some Insiders seeing their Start menu layout being reset after upgrading to the previous flight.

• We fixed an issue resulting in miniview windows (for example in Movies & TV or Skype) flying offscreen when attempting to be resized in the last few flights.

• We fixed an issue where clicking search results for settings in Settings in the last few flights would always take you to the top level category in the last few flights, rather than the actual category you searched for (for example, Display Settings instead of Storage Settings).

Here are the known issues:

• If you are experiencing broken functionality in Mail, Cortana, Narrator or missing some features like Windows Media Player, please see this Feedback Hub post:https://aka.ms/Rsrjqn. While this issue has been addressed, if you ever upgraded from 16299.xx to 16299.15 (and then to newer builds) you may still need to take the steps to get your PC back into a good state.
• Popular Tencent games like League of Legends and NBA2k Online may cause 64-bit PCs to bugcheck (GSOD).
• VPNs which use custom pop-up windows during connection attempts may fail to connect with error 720.
• Due to a bug that was introduced on this build, you may not receive all of your notifications from Cortana. Reminders are unaffected by this bug, but you may not receive other Cortana notifications that you are expecting. The fix for this should be in the next flight.
• [DEVELOPERS] Deploying an x86 app to a x64 PC remotely result in “FileNotFound” deployment failures if the target PC is running Build 17040. Deploying an x64 app to a x64 PC remotely or a x86 app to a x86 PC will work fine.
• All types of dynamic volumes listed here will not mount properly or be accessible from Windows. The data remains intact on the volume, it is just not accessible from this OS build. If you need access to the data you can roll back to an earlier build. A fix for this issue will be released in the next build.
• After upgrading to build 17035 or later you may lose certain dictionary files, resulting in not being able to input Japanese or Traditional Chinese via IME, Touch Keyboard, or Handwriting if you are using a non-Japanese or non-Traditional Chinese language-based OS (like an English-based OS). We are working to fix it. In the meantime, this should help to get you unblocked:
  1. Go to Start > Settings > Time & Language > Region & language​.

  2. Under Language, select your language (e.g. “Japanese”).

  3. Click [Option] and if the [Download] button is available for “Basic typing” under the Language options, please click it to start download.

  4. Once the dictionary files have been downloaded, you can check the status of the necessary optional feature in Settings > Apps > “Apps & features” > “Manage optional features”. The name will be something like “Japanese typing” or “Chinese (Taiwan) typing”.

It's always recommended that you read through the known issues before installing a build, so that you know if the risk is worth the reward. As you can see, some of them have workarounds, but many of them do not.

You can install build 17046 by going to Settings -> Update & security -> Windows Update -> Check for updates. If you're not on the Fast ring just yet, you can sign up by going to the Windows Insider Program tab and clicking 'Get started'.
