Announcing Windows 10 Insider Preview Build 15058 for PC

UPDATE 3/17: We have released Windows 10 Insider Preview Build 15058 for PC to Windows Insiders in the Slow ring. 

Hello Windows Insiders!

Today we are excited to be releasing Windows 10 Insider Preview Build 15058 for PC to Windows Insiders in the Fast ring.

Other changes, improvements, and fixes for PC

  • We fixed the issue causing a number of inbox apps to fail to launch (such as Store) and preventing any app updates from the Store from installing.
  • We fixed another issue causing some UWP apps would unexpectedly appear with their app package name in the title bar as opposed to the app name.
  • We fixed an issue where going to fullscreen or maximizing Microsoft Edge when Microsoft Edge’s window was snapped to a size smaller than half the screen would trigger back navigation.
  • We fixed an issue resulting in the mouse pointer staying visible when watching a video fullscreen in Microsoft Edge.
  • We fixed a crash Insiders may have sometimes experienced in recent builds when accessing the Wi-Fi Settings page via Settings > Network & Internet > Wi-Fi.
  • We fixed an issue where the desktop session sometimes crashed for Insiders after locking if the PC was set to lock on sleep. After this happened, trying to unlock the computer could result either seeing an unexpected “Can’t log in: The number of connections to this computer is limited and all connections are in use” error on the login screen, or a successful login only to find all open apps had been closed.
  • We fixed an issue where renaming an encrypted PDF would reset the default PDF reader if it was not currently set to Microsoft Edge.
  • We have improved video playback quality on the target device when using Miracast to wirelessly connect from a high DPI PC to another high DPI device.

Known issues for PC

  • Some PCs may fail to update to Build 15002 and higher due to SYSTEM_PTE_MISUSE error.
  • Some apps and games may crash due to a misconfiguration of advertising ID that happened in a prior build. Specifically, this issue affects new user accounts that were created on Build 15031. The misconfiguration can continue to persist after upgrading to later builds. The ACL on the registry key incorrectly denies access to the user and you can delete the following registry key to get out of this state:


  • There is a bug where if you need to restart your PC due to a pending update like with the latest Surface firmware updates, the restart reminder dialog doesn’t pop up. You should check Settings > Update & security > Windows Update to see if a restart is required.
  • [GAMING] Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.
  • Issues may occur when exploring pages using the F12 Developer Tools in Microsoft Edge with cross-origin iframes (e.g. the DOM explorer shows only the iframe DOM, the Console frame selector doesn’t list the iframes, etc.).
  • Surface Pro 3 and Surface 3 devices will fail to update to new builds if a SD memory card is inserted. To take a new build, remove the SD memory card. You can re-insert the SD memory card after the latest build is installed.

Community Updates

Windows Insiders, we LOVE to hear your stories and it’s always such a pleasure to hear what you’re using your technical superpowers for in your communities. Today, we’d like you to meet Mauricio Uribe, one of our Insiders hailing from Bogota, Colombia who teaches young people to code in his spare time. We sat down with Mauricio during a Windows Insider Meet Up in February in Colombia. His passion for technology, his drive to help local children learn to code, and his infectious energy for life make Mauricio both a great conversationalist and an influential Windows Insider.

Meet Mauricio Uribe

As with many of our Insiders, Mauricio grew up with a love for Windows and technology and has remained an active supporter over the years. “I have been passionate about computers since I was 13 and technology became my main hobby. I’ve seen the birth and transformation of Microsoft Windows since its first version, and was actually an organizer for the official launch of Windows 95 in Colombia.”

One of the many things we loved about Mauricio were his insights into how technology has made a difference in the world. “I love evolution. I love computers. I love that technology is changing the lives of all people.” He spoke of Microsoft’s renewed focus in the developer space, buoyed by the announcements of BASH coming to Windows and the future of further cross platform and system partnerships. “I love the way Windows is focusing its vision right now.”

On top of his day job, Mauricio helps children in his city, like his seven-year-old daughter, follow their dreams of becoming the future leaders in technology and coding. “I am currently the CEO of a private mining company, but despite not being a systems engineer I taught Introduction to Computers at the Universidad Javeriana where I instructed students on the basics of computing like DOS, Lotus, and WordPerfect.” Mauricio continues to learn, grow, and share with his community so that others around him can kick-start their own technology careers.

“My main interest in learning to code is that I want to teach my daughter. And as soon as I finish my coding course and get my diploma, I plan to develop the same course I’m taking but in Spanish for kids. I want to make it available to the public so people can see that it’s possible to learn to code in a fun way.”

Mauricio proudly identifies as a Windows Insider and we are lucky to call him a champion. Between his work advocating for the program in Bogota and his help in getting our Insiders motivated, Mauricio’s leadership is creating a vibrant Insider community in Colombia.

Have a great week everyone keep hustling,
