Bugs and quirks

 * At the time of release, the update process had a chance of hanging for extended periods of time when attempting to install this build.
 * Some pinned websites do not work with the new taskbar experience.
 * Live preview doesn't work for pinned site tabs.
 * Pinned sites don't show all open tabs for a domain. A workaround with this issue is to pin the site’s home page rather than a specific page.
 * Syncing may not work properly in the Mail app with certain mail services.
 * If you open an Office document from File Explorer, it may appear to be blank. To workaround this issue, open the selected document from the app instead.
 * Some Office applications may either crash or go missing if you update to this build.
 * Some devices may randomly encounter an  BSOD.
 * There's a chance of the Settings app crashing if you open Manage Disks and Volumes.
