*) Changed the default state of the Handwriting Panel to be floating next to the text field, rather then docked at the bottom of the screen.
*) Moving some things around in Storage Settings;
*) In previous build the Power Settings may not be preserved. This should be re-applyed after the upgrade;
*) Fixed an issue where the Virtual Touchpad’s left and right buttons might not work on some devices;
*) Fixed an issue where the Virtual Touchpad wouldn’t launch if the primary monitor was non-touch, and added the Virtual Touchpad icon to the Taskbar settings where you can Turn system icons on or off;
*) Fixed the issue where apps such as Store, Photos, and People might launch on their own after your PC had been inactive for a period of time;
*) Fixed the issue where navigating to Settings > System > Battery would crash the Settings app;
*) Fixed an issue where using ~ to switch languages using the Thai keyboard when typing in Office apps, such as Outlook or Word 2016, might sometimes result in a hang;
*) Fixed an issue where double-clicking on an Excel document to open it from File Explorer would crash Microsoft Excel;
*) Fixed an issue where Windows Hello might get stuck ''Looking for you'';
*) Fixed an issue Insiders with Surface Dial may have experienced recently where rotating the Dial could result in unexpected beeps;
*) Fixed an issue where the PowerShell entry in File Explorer’s File menu would sometimes be unexpectedly greyed out;
*) Fixed an issue where the Clock and Calendar flyout in the taskbar wouldn’t launch when the display language was set to Chinese (Traditional) and the system was using the phonetic sorting method;
*) Fixed an issue where some notifications might draw too high or too low, and then be seen moving itself to the correct position;
*) Fixed an issue where the outline incoming notification toasts could still be seen if notification banners as a whole for that particular app had been turned off;
*) Fixed an issue Insiders may have experienced where the Favorites bar on desktop might appear empty, despite having items in the Favorites folder;
*) Fixed an issue that could result in CPU throttling when idling on certain webpages with many gifs or looping videos in Microsoft Edge;
*) Fixed an issue that could result in Alt + D sometimes not being able to set focus to the address bar in Microsoft Edge;
*) Fixed an issue resulting in Microsoft Studios games like Microsoft Sudoku, Jigsaw, Minesweeper, Taptiles, and Treasure Hunt potentially freezing at the splash screen on launch;
*) Fixed an issue where, if the taskbar location was set to be on top, it was visible on the Welcome screens after upgrading.

Known issues
*) Using keyboard monitor hotkeys to adjust brightness won’t work as expected. Desired brightness change could be done via the Action Center or by going to Settings > System > Display;
*) You may see a popup ''Catastrophic Error'' dialog when opening OneDrive folders. If you do, the workaround is to open an elevated Command Prompt or PowerShell window and enter ''attrib -O '';
*) DirectAccess isn't working for some windows Insiders;
*) When using Microsoft Edge with Narrator, you may hear ''no item in view'' or silence when tabbing or using other navigation commands. You can use Alt + Tab when this happens to move focus away from and back to the Edge browser and then Narrator will read as expected;
*) Hey Cortana, play on doesn’t work immediately after installing the app. Wait 5 minutes for indexer to kick in and try again;
*) The windows Defender Dashboard is primarily aimed at providing some minimal read-only status for Antivirus/Firewall, with some very limited functionality for interacting with the app.


This is a fast ring build, which updates via Windows Update from an earlier build.
Or you can convert the .ESD to .ISO and use it as a fresh install.

Crashing of Apps (UWP or Win32)
This build tends to crash on using UWP of Win32 apps or randomly after a few clicks, there is no pattern to it.
It could be that it works fine for other people, it is different per installation.
