Changes[edit | edit source]

The Books pane in Microsoft Edge can now be refreshed using a pull gesture.
When an e-book is pinned to the Start menu from Microsoft Edge, you will now see a live tile that cycles between the book cover and the current completion progress.
Added a new option to choose the scale of the print-out when printing PDF files from Microsoft Edge (actual size or fit to page).
Updated Timeline to include the ability to cycle through Sets tabs in addition to being able to see the number of tabs to restore with a Sets session.
If Windows Subsystem for Linux is enabled, a new option to open a new Linux shell will be added to the right-click menu that appears if you press ⇧ Shift on a blank area in File Explorer.
Added preliminary support for same-site cookies in Microsoft Edge and Internet Explorer 11.
If a Bluetooth device is running low on battery, a notification will appear to alert the user.
When you hover over the leaf icon in the Status column in Task Manager, a tooltip will appear to describe what it means (this app is suspending processes to help improve system performance).
General improvements, changes and bug fixes listed in the official announcement.

Bugs[edit | edit source]

General[edit | edit source]

Narrator can read extra text when Alt+Tab ↹ is invoked.
Dark theme support is incomplete in File Explorer and the Common File Dialog.
If you use Remote Desktop, project the screen, or use multiple monitors, there's a chance of Explorer.exe hanging. Microsoft Edge can also hang in a similar fashion with this issue.
You cannot enable Developer Mode through the For developers Settings page in this build.

Sets & Office[edit | edit source]

The top of some Win32 desktop apps may appear slightly underneath the tab bar when they're opened maximized. To fix this issue, restore and re-maximize the affected window.
Sometimes closing one tab can minimize the entire set.
Tiling and cascading windows do not work for inactive tabs.
Opening an Office document while the same app has an existing document open may cause an unintended switch to the last active document. It can also happen if you close a sheet in Excel while other sheets are open.
Locally stored files and cloud files that are on non-Microsoft cloud services are not automatically restored.
