What’s new on Windows 10 build 17639
Here are all the changes Microsoft is making available with this new preview of Windows 10 version 1809 expected to release in October 2018:
In this flight, Sets, the tab experience for apps, documents, and websites, is getting a slew of improvements and tweaks, including:
Drag and drop: You can now drag an app tab around within the Set or combine tabbed app windows into Sets.
Alt + Tab: It’s now possible to use Alt + Tab keyboard shortcut to circle between open tabs. (If you have multiple Microsoft Edge windows in a Set, only the one most recently accessed will be visible in Alt + Tab.)
Sets context menu: If you right-click a tab, you’ll find additional options, including “close other tabs”, “move to new window”, and “close tabs to the right”.
In the Previous Tabs experience, you’ll find these changes:
You can now pick and choose which Previous Tabs you want to restore, instead of only being able to restore all tabs.
You can now restore Previous Tabs from any type of activity.
When you open a document that previously had tabs, a prompt will appear offering to restore those tabs, and the Previous Tabs button will be in the filled state. If it’s not a document, a prompt will not show automatically, but you’ll know that there are tabs available to restore because the Previous Tabs button will be in the filled state.
There’s a new animation when there are no Previous Tabs available to be restored.
As part of the new Set improvements, File Explorer is also getting several new shortcuts:
You no longer need to hold the Ctrl key on the new tab page to launch a File Explorer window in a tab.
You can now open new tabs using File Explorer menu.
Right-clicking on a folder, the context menu includes an “Open in new tab” option.
A new Ctrl + T keyboard shortcut to open a new tab when a File Explorer window is in focus. This is in addition to Ctrl + N to open a new window, and Ctrl + W to close the window or tab.
In this Redstone 5 flight, Windows 10 is updating the Sets settings page (Settings > System > Multitasking), and in addition to an option to enable and disable the feature, you can decide the Alt + Tab action, and it’s possible to specify which apps don’t use tabs.
Microsoft also notes that on build 17639, you’ll notice that Sets looks a little more polished, and switching between tabs is a lot smoother.
Alongside the improvements on Sets, on the Settings app, the Bluetooth & other devices page now display the batter level for supported Bluetooth devices.
Starting with Windows 10 build 17639, Control Panel no longer includes the settings to adjust brightness, but these settings can already be configured in the Settings app that will eventually replace Control Panel.
