New features and changes[edit | edit source]

Microsoft Edge improvements[edit | edit source]

Redesigned the Hub view in Microsoft Edge. The Hub sections are now listed with their full name visible in the navigation view to the left. It can be collapsed to show icons only.
Microsoft Edge can now save and automatically fill in card information on payment web forms.
Redesigned the look and feel of Reading View and the Books experience across all EPUB and PDF books, documents or web pages.
Added a new pop-over menu for Notes in Books, making it easier to navigate between annotations, notes, or highlights. The seek bar was updated, and support for Go-to-page (Ctrl+G). Go-to-page also supports PDF page labels and EPUB page list, so the page numbers can correspond to a print source that may be numbered differently.
Added Grammar Tools for EPUB books and Reading View. It helps to break the words on the page into syllables, as well as highlight other parts such as nouns, verbs, and adjectives.
You can make books, PDFs and Reading View pages full-screen.
Reading progress, notes, bookmarks and annotations are now roamed much quicker across devices on the same account in near-real time via WNS.
General improvements to fixed layout EPUB books.
When you're reading an ebook, a book icon is shown, along with the title rather than the URI.
Added support for audio narrated books (EPUB Media Overlays). Accessibility improvements were made when using Narrator to browse, search or load a book.
The favorites bar will now always show if there's at least one favorite in it.
An option was added to never save passwords for domains.
You can now autofill saved passwords when you're using InPrivate mode, as well as use extensions in said mode.
Added support for CSS extensions for OpenType font variations. This allows single "variable" font files to behave like multiple fonts, with a range of weight, width or other attributes.
The Microsoft Edge Developer Tools can now be docked vertically.

Windows Shell improvements[edit | edit source]

Added Quiet Hours (later renamed to Focus Assist). This feature blocks certain notifications from appearing based on priority. It can also be made to focus only on alarms.
If upgraded from another Windows OS, the Documents and Pictures folders are shown on the Start menu by default. This only applies to upgrade installations, it does not apply to clean installations.
Improvements to Near Share.

Settings improvements[edit | edit source]

You can now find language packs through the Microsoft Store and the Region & language section of the Settings app.
Disk Cleanup functionality has been added to Storage Settings.
Improvements to the Sound Settings page. It added a new "App volume and device preferences" page to help customize the user's audio experience.
Added the ability to copy the device's name in the About section, as well as adding a link to System info and updated the search strings, so if you search for "computer name", you will see a link to About Settings.
Added the ability to turn on or off app execution aliases (a name declared to run an app from Command Prompt).

Input improvements[edit | edit source]

Introduced the Embedded Handwriting Panel. This feature is only accessible if you are using a pen to interact with the text field - if you use touch, the standard handwriting panel will be used instead.
Windows now recognizes Hindi handwriting, as well as Welsh, Sesotho, Wolof and Maori.

Other changes[edit | edit source]

Minor changes to the Camera app, it now remembers the last camera and scene that was used. Made some changes regarding handling two cameras simultaneously, and added some more resoultion options. Changes were made to the core of the app to remove handling for unsupported devices and redundant functionality.
Rolled out Sets to more Windows Insiders (at the time of this build's release).

Bugs[edit | edit source]

You can't open a InPrivate Microsoft Edge window from a Mixed Reality headset. A regular window gets created instead.
There's a "Use OpenSSH (Beta) for remote deployment" switch in Settings. It is non-functional and turning it on will break remote deployment to the system until its turned off.
Timeline may not be visible immediately after upgrade. If this bug is encountered, wait 15 to 30 minutes and then try again.
The Windows Defender icon is missing from the system tray, even if it's shown to be enabled in the Settings app.
Certain devices may freeze on the boot screen after upgrading. If this occurs, go to the BIOS and disable virtualization. This issue was fixed in this build's later compile.
Apps that come bundled with Windows may fail to update in the Microsoft Store, giving out error code 0x80073CF9 instead of updating the app.
Audio playback from Microsoft Edge is sometimes unexpectedly muted.
Updating to this build sometimes breaks camera and microphone access, and Settings can crash when you toggle those items back on. To workaround this bug, input the following in an admin Command prompt: reg add HKLM\Software\Microsoft\Windows\CurrentVersion\CapabilityAccessManager\ConsentStore\microphone /v Value /d Allow /f.
Win32 apps pinned to the Start menu have blank live tiles that show only a name starting with "W~".
Word documents with add-ins running will have problems saving.
