Changes[edit | edit source]

A dialog has been added when Adobe Flash content is blocked in Microsoft Edge. It is located in the URL bar.
When reading a locally saved EPUB book in Microsoft Edge, A book icon is used in place of the previous generic icon.
If you switch pages while an EPUB book is being read, the reader will jump to the specified page.
If you've changed the read aloud settings when reading an EPUB in Microsoft Edge, the settings you chose will now be preserved for other e-books that are opened afterwards.
Removed the watermark and timebomb temporarily.

Bugs[edit | edit source]

Some machines may still experience constant crashes with the Spectrum.exe service, causing PCs to lose audio, disk I/O usage to become very high, and apps like Microsoft Edge to become unresponsive when doing certain actions. To fix this, stop the Spectrum service, navigate to C:\ProgramData\Microsoft\Spectrum, delete the PersistedSpatialAnchors folder and reboot.
Some games might minimize to the taskbar when launched.
Microsoft Edge F12 tools may intermittently crash, hang, and fail to accept inputs.
The icon for the Windows Insider Program under Settings → "Update & security" is shown as a square instead of its usual icon.
Windows Hello authentication may not work on some Surface Pro 4 and Surface Book devices.
Microsoft Edge and/or the taskbar may randomly stop responding. If that happens, open Task Manager via Ctrl+⇧ Shift+Esc and close Microsoft Edge and restart explorer.exe.
