Microsoft has released Windows 10 Insider Preview Build 17046 for PC to Windows Insiders in the Fast ring. nice new stuff for Edge & input enjoy upgrading & testing!

What’s new in Build 17046

Microsoft Edge Improvements

Form Fill for Address fields: Microsoft Edge can now save and automatically fill your preferred information in addresses and related forms. When filling in fields on a form, such as an address or other contact information, Microsoft Edge will prompt to save your form information. In the future, you can simply select the preferred information from a drop-down menu to complete all the related fields.

Addresses you save will be roamed between your Windows 10 devices, and you can manually add or remove form entries in Advanced Settings.

Text Spacing comes to Reading View: Much like when reading an EPUB book, you can now adjust the text spacing when you’re in Reading View. To enter Reading View, open an article or blog post you’re interested in, then tap the book icon next to the address bar. Adjusting the page to use wider spacing can improve reading fluency.

Windows Shell Improvements

Access advanced UWP app options right from Start: We’ve added a new quick way to get to advanced options! Rather than click through Settings > Apps > Apps & Features > (finding your app) > Advanced Options, if you right-click a UWP app or UWP app tile in Start with this build you’ll find a new Settings option under More which will take you straight there, where you can repair, manage app add-ons, and see startup tasks (if available). We have a goal to make this page the one stop shop for all of the app-related settings you can find across Settings – the Startup tasks work was the first part, but there’s more to come, stay tuned!

Input Improvements

Emoji data overhaul for the touch keyboard: We’ve taken a look at the emoji data across all of the languages we support and have updated it so that more of the emoji you love will appear as you’re typing related words with the touch keyboard. We’ve also added support for a number of languages that didn’t previously support emoji candidates. Please give it a try and let us know how it goes! Try typing words like unicorn, kiwi, artist, or turtle (in your language, of course ????) – primary candidate will be listed in the candidate list, any secondary candidates will be listed in the candidate list once you tap the emoji button. We still have a bit more work to do on the data that will come with a later flight, but you should see a noticeable improvement with this build.

This flight includes new and updated emoji data for over 150 languages including: Arabic (Saudi Arabia), Danish (Denmark), German (Germany), Greek (Greece), English (Great Britain), Spanish (Spain), Spanish (Mexico), Finnish (Finland), French (France), Hebrew (Israel), Hindi (India), Italian (Italy), Dutch (Netherlands), Norwegian (Norway), Polish (Poland), Portuguese (Brazilian), Portuguese (Portugal), Russian (Russia), Swedish (Sweden), and Turkish (Turkey).

NOTE: To see the emoji predictions as you type in a particular language, as well as typing predictions, you will need to have the optional typing feature applied for that language. It should download on its own as long as you have internet connection when you add the language to your language list, or once you connect to the internet thereafter. If you’re not seeing predictions and have internet connectivity, try removing the language and then adding it back again.

Now you can use Emoji Panel to insert a bunch of emoji at once! Based on your feedback, we’re adjusting the design of the Emoji Panel so that after opening up the panel by pressing hotkey Windows logo key + “.” or “;”, you could browse, search and then select more than one emoji. The panel won’t go away until you click close button or press “Esc” key.

Note: The Emoji Panel is currently only available when the en-us keyboard is active.

Keyboard Improvements: We’re introducing a new keyboard for Tamil language called Tamil 99, as well as updated Sinhala, Myanmar, and Amharic keyboards

• Tamil 99 keyboard (hardware keyboard, touch keyboard) is now available on Windows PC! We’ve added a new Tamil keyboard – if you speak this language and would like to try it out, make sure Tamil (India) is in your language list. Click that language entry in Region & Language Settings, then select Options > Add a keyboard > Tamil 99. Here’s an example of how it looks on the touch keyboard:
  
• The Sinhala and Myanmar keyboards have been updated to support more comprehensive ways of inputting sequences, for example these now work: Sinhala: ෙ + ක -> කෙ, Myanmar: ေ + မ = eမ
• In order to improve the Amharic typing experience, we’ve fully updated the Amharic keyboard so that you can now input compositions more comfortably. Instead of seeing English letters and a dropdown list of candidates while you type, you’ll now see the Amharic script directly inserted into the text field.

We would love to hear your feedback as you try out these changes!

General changes, improvements, and fixes for PC

• 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).

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

What’s new in Build 17040

Settings Improvements

Adjust the brightness of SDR content on your HDR display: Starting with Build 17040, Windows now lets you adjust how bright SDR content appears when running in HDR mode on the desktop. On an HDR capable system, you will see a slider in the “HDR and advanced color settings” page under Settings > System > Display. This is one of the improvements to HDR image quality that we have planned based on feedback from Insiders.

New Cursor, pointer, and touch feedback section in Ease of Access Settings: Continuing our recent efforts to reorganize this section in Settings, you’ll notice that “change cursor thickness”, “Change pointer size and color”, and “Change touch feedback” have been moved to this new place.

Touch keyboard Improvements

Shape-writing with wide touch keyboard: With the Fall Creators Update we introduced shape-writing input for one-handed keyboard. We’ve heard your feedback, and with today’s build we’re happy to announce that it’s now also available when using the wide keyboard!

As a reminder, shape-writing is currently available for the following languages: Catalan (Catalan), Croatian (Croatia), Czech (Czech), Danish (Denmark), Dutch (Netherlands), English (India), English (United States), English (United Kingdom), Finnish (Finland), French (Canada), French (France), French (Switzerland), German (Germany), Greek (Greece), Hebrew (Israel), Hungarian (Hungary), Indonesian (Indonesia), Italian (Italy), Norwegian, Persian (Iran), Polish (Poland), Portuguese (Brazil), Portuguese (Portugal), Romanian (Romania), Russian (Russia), Spanish (Mexico), Spanish (Spain), Swedish (Sweden), Turkish (Turkey), and Vietnamese (Vietnam).

Handwriting panel Improvements

Improved Insertion Gesture: Based on your feedback about gesture recognition, we’ve updated the insertion gesture (to add space between words or letters) to now be a small caret (see below gif for a demo of what it looks like, along with a cameo of our joining gesture).

A New Commit Gesture: We’ve added a new gesture so you can automatically commit your text and clear out the text in the handwriting panel. This gesture looks like a 90 degree angle bracketing the end of your text – see gif below for an example of how it works.

Improved button layout for Chinese (Simplified) Handwriting: If you use Chinese (Simplified), you’ll now see a layout similar to the one announced for other languages with Build 17035. The buttons in the handwriting panel are collapsed by default – tap the button with the ellipsis to expand them.

General changes, improvements, and fixes for PC

• 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 network profiles might change from Private to Public after upgrading to the previous build.
• We fixed an issue resulting in checkboxes being missing from certain win32 apps.
• We fixed a typo in the Windows Defender Security Center’s Controlled Folder Settings.
• We fixed an issue resulting not being able to fully remove Windows.old in the last two flights.
• We fixed an issue resulting in Narrator not saying anything when the candidate bar for hardware keyboard prediction opened. We also fixed an issue where Narrator wasn’t reading the word candidate when the focus moved into candidate bar.
• We fixed an issue where the “Working on updates” screen was black with a small theme colored box instead of entirely theme colored.
• We fixed an issue resulting in some Insiders experiencing a green screen on the previous flight with the error BAD_POOL_CALLER.
• We fixed an issue resulting in UWP app sometimes leaving drop shadow leftovers after closing the window.
• We fixed an issue where inactive window scrolling wouldn’t work if Excel 2016 was in focus.
• We fixed an issue resulting in a noticeable flicker when using hotkeys or a precision touchpad to switch between virtual desktops.
• We fixed an issue where the XAML Reveal light wouldn’t follow your mouse until the first mouse click – instead showing the entire element lit. This issue was visible in Settings and other XAML based UI in the last few builds.
• We fixed an issue resulting in changes to Feedback Frequency in Feedback & Diagnostics Settings not persisting after leaving the page and returning.
• We fixed an issue where Start wouldn’t open if you pressed the Windows key when the system menu from elevated Command Prompt or Task Manager window was open.
• We fixed a rare issue where if you had certain streaming-capable apps on your PC before upgrading you might end up seeing a black screen with only a cursor for some time after logging in.
• We fixed an issue from recent flights where the “Add” button in the PIN section of Sign-in Option Settings didn’t work for local accounts.
• We’ve updated the icon for Collections in Cortana.
• We’ve updated the touch keyboard so that the margin between each key is visual only. This change will be noticeable if you accidentally overshoot the key press by just a tiny bit – before it might seem as if key presses were being dropped in this scenario.
• Based on your feedback, the feature to restore applications that have registered for application restart after you reboot or shutdown (through power options available on the Start Menu and various other locations) has been set to only occur for users that have enabled “Use my sign-in info to automatically finish setting my device after an update or restart” in the Privacy section under Sign-in Options Settings.
