Quick look at the new Cortana and logon screen features found Windows 10 "Redstone" (build 14279) for PC.

Microsoft released Windows 10 build 14279 to the Fast ring of updates for PC. The new preview part of the Redstone update includes a number of improvements and changes on Cortana, and the company is also introducing new tweaks in the Lock and Logon screens.

In addition, build 14279 brings several new fixes on Microsoft Edge, desktop, and driver crashes that was causing blue screen on certain devices. The new Insider preview ships with a few known issues on Surface Pro 3, Surface Pro 4, and problems with Kaspersky antivirus, and a number of other issues.

Here’s the list with all the changes for the new build:


  • Cortana now brings support for additional languages, including Spanish (Mexico), Portuguese (Brazil) and French (Canada)
  • Users can now create Cortana reminders without having to specify date, time, or location.

User interface

  • Microsoft introduces new logon screen. Now the logon screen has the same image as the Lock screen.
  • Spotlight currently doesn’t show a background in the logon screen.


  • Messaging + Skype on Windows 10 now syncs messaging history on both PC and mobile.
  • Photo app includes new Sway integration.

  • Fixed issue where Cortana would continue to show reminders that have been completed.
  • Fixed issue where items copied/moved to the desktop would not display until the desktop is manually refreshed.
