Known issues

• We’re working on a fix for an issue where some Microsoft Store games protected with Easy Anti-Cheat may fail to launch.
• We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• If you are impacted by an issue where when pressing space while using the Korean IME in Edge and Chrome the last character was deleted, this has been fixed in Chromium as part of Bug 1099125. We’ll be removing this from the known issues with the next flight.
• We’re working on a fix for an issue where the min/max/close buttons are stuck in their original positions after resizing a UWP app. If you move the app window the position should update.
• We’re investigating reports that the new taskbar experience described above isn’t working for some pinned sites.
• We’re working on a fix for an issue where sometimes the “close all windows” action in the taskbar doesn’t close not all of the open tabs
• We’re working on a fix to enable live preview for pinned site tabs.
• We’re working on enabling the new taskbar experience for existing pinned sites. In the meantime, you can unpin the site from the taskbar, remove it from the edge://apps page, and then re-pin the site.
• We’re working on a fix for an issue where pinned sites don’t show all open tabs for a domain. In the meantime, you can fix this by pinning the site’s homepage rather than a specific page (e.g. pin microsoft.com rather than microsoft.com/windows).
• We’re working on a fix for an issue where Alt + Tabbing to a browser tab sometimes moves the previously active browser tab to the front of the Alt + Tab list as well.
