Windows 10 Anniversary Update drawing ever nearer, Microsoft is hard at work squashing as many bugs as it can.

Naturally, this means new builds released to Windows Insiders won’t offer any significant new features, but they will contain important fixes, general improvements and welcome performance boosts.
The latest PC and Mobile builds — 14366 and 14364 respectively — arrive in the Fast ring today, and kick off the Windows 10 Anniversary Update June Bug Bash. Over the next four days, Microsoft is seeking help identifying and squashing as many bugs as possible, via quests open to Insiders.

So what’s new in the latest builds? There’s a Windows Store update which offers performance and stability improvements, and a new Office Online extension for Microsoft Edge which will let you use Word, Excel, PowerPoint, OneNote and Sway Online without needing Office installed. You can find out more about this extension, and others, here

Improvements and fixes for the PC build include:

  • For you mes amis: If you have a French Windows 10 Insider Preview build installed on your PC, you should receive this build as Microsoft has fixed the issue with the French translation process that caused a lot of text to revert from French back to English.
  • Navigating to the Privacy pages in Settings app will no longer crash the Settings app and prevent you from adjusting your privacy settings.
  • Microsoft has fixed the issue causing PC and Mobile devices trying to project to a PC (via the new PC Access feature) to fail.
  • Microsoft has fixed the issue where Start would not launch while an app is installing for certain languages, such as Chinese or Portuguese (Brazil).
  • Microsoft has updated the size of the Windows Ink Workspace icon in the notification area on the taskbar to be more consistent with the other notification area icons. In a similar drive to improve the consistency of the experience, Microsoft has updated the X to leave the Windows Ink Workspace which will now show a red state when you hover over it. It also fixed an issue where mouse wheel scrolling wouldn’t work to spin the ruler with certain mice, and an issue where dismissing the share pane or accepting the prompt to enter tablet mode would result in exiting the Windows Ink Workspace.
  • Microsoft has updated Cortana search results, so now when you right-click on a .docx file, you’ll see a context menu option to open that file’s location.
  • Microsoft has fixed an issue resulting in the monitors in under Settings > System > Display from sometimes jumping to a different ordering after being clicked and causing scaling changes. It also fixed an issue where the slider to change display scaling might jump to an unexpected scale factor as you were moving it.
  • Microsoft has fixed an issue resulting in not being able to unsnap a full screen Remote Desktop window if you had been prompted credentials while connecting.
  • Fixed an issue when the tile names could become cut off after using semantic zoom, and one where Start tiles could no longer be moved with touch.
  • In an effort to improve visibility and access to your newly installed apps, Microsoft has moved the “Recently added” section of Start to be located above the “Most used” section in the All apps list. Microsoft has also increased the duration of time in which apps will be listed here — now 7 days, so you can easily try them out and decide if you want to pin them to Start or the taskbar for regular use and quick access.
  • Microsoft has fixed an issue where an active VPN connection could block the PC from going from idle into sleep.
  • Fixed an issue where the touch keyboard might appear on the Lock screen after pressing the Num-Lock key on the keyboard.
  • Fixed an issue that could result in Microsoft Edge using a large amount of CPU when open to a page with many animated gifs, as well as an issue resulting in certain captchas not displaying correctly.
  • From this build on your default location will now be preserved across build updates.
  • Microsoft has fixed an issue resulting in nothing happening if you attempted to expand a Skype notification in Action Center. Also fixed an issue where the scrollbar would draw with no margin from the chevron and X in Action Center notifications, and one where app logos might be missing from the Action Center.
  • Fixed an issue resulting in the cursor not showing up when interacting with the system using a Wacom tablet.
  • Fixed an issue where the Settings app could open to a blank page after selecting a settings page via search results.
  • Fixed an issue where the File Explorer window might navigate back to Quick Access after deleting something from the current folder in view. Microsoft has also fixed an issue where right-clicking on the desktop might result in showing a spinning curser for a long time before the context menu would show.
  • Fixed an issue resulting in existing reminders failing to display in the Cortana UI, and an error when attempting to save a new reminder.
  • Microsoft has updated the Mobile Hotspot settings page to allow name, IP address, and mac address to be selectable so it can be copied elsewhere if needed.
  • Fixed an issue where the battery flyout might not report the correct overall charging state for devices with two batteries.
  • Fixed an issue where the title bars of apps using dark theme wouldn’t be dark when the window was not in focus, for example, Groove Music or Settings app.
  • Fixed an issue resulting in you sometimes seeing a progress indicator before the background image would load on the Lock screen.

Improvements and fixes for the Mobile build include:

  • Made some fit-and-finish updates to the Settings app such as tightening the spacing between checkboxes (like on the Sounds settings page). Also fixed an issue where settings pages wouldn’t show a progress indicator if they needed a while to load.
  • Fixed an issue where a number of app logos were missing from notifications, despite them being visible in the Action Center.
  • Fixed an issue where the Alarms and Clock Live tile would still show that an alarm was active after a one-time alarm had gone off and been dismissed.
  • Fixed an issue where Cortana would prompt you to unlock your device before reading a text over Bluetooth.
  • Fixed an issue resulting in Microsoft Edge crashing when trying to scroll certain webpage.
  • Fixed an issue where disconnecting from Bluetooth speakers would result in the phone being set to vibrate if it hadn’t already.
  • Fixed an issue where the page to manage cross-device notification settings in Cortana was blank.
