Microsoft has released build 14379 for Windows 10 Insiders for PC and Mobile. As the Anniversary Update is coming in a month (August 2nd), they are now in bug squash mode. A few fixes this time:

Improvements and fixes for PC

• We fixed an issue where the size of the Credential UI might not be big enough to display the contents on a PC with High DPI.
• We fixed an issue where Action Center might crash after dismissing a large number of notifications.
• We fixed an issue where Centennial app launches from Start or Cortana wouldn’t count towards those apps bubbling up in Start’s “Most used” list.
• We fixed an issue where no note would have keyboard focus after minimizing then reopening the Sticky Notes app.
