Contrary to popular belief I did not push the red button that has sent Windows 10 Build 10586 to Windows Insiders today but I have seen the actual button that does the job this week while I have been on the Microsoft Campus.

Windows Insiders in the Fast Ring will find build 10586 on their Windows 10 systems ready to install this morning and it is likely the final pre-cursor to the expected Threshold 2 release later this month.

According to Microsoft this is a build which is focused on bug fixes and general improvements.

What is great about this build from the Windows team is that there are only tow known issues that can impact users:

  • After upgrading from one Windows 10 Insider Preview build to another Insider Preview build, Skype messages and contacts will disappear from the Messaging + Skype app. You can get Skype messages and contacts back by navigating to “C:\Users\<USERNAME>\AppData\Local\Packages\Microsoft.Messaging_
    8wekyb3d8bbwe\LocalCache” in File Explorer and deleting or renaming the “PrivateTransportId” file. After deleting or renaming that file, go to the Skype video app and sign out of Skype and sign back in.
  • The Insider Hub might be gone after upgrading to this build. You can get Insider Hub back by going to Settings > System > Apps & features and clicking “Mange optional features”, choosing “Add a feature” and selecting Insider Hub.

On the flip side several lingering issues have been sorted out in this release:

  • The issue where any audio playing (like music from Groove, or videos from the Movies & TV app) gets reduced by 75% for a period of time after a notification pops up from Action Center is fixed.
  • Pressing the power button on your Surface Pro 3 should put your Surface Pro 3 to sleep instead of shutting it down.
  • We fixed an issue reported by Windows Insiders where a disksnapshot.exe command prompt window would flash randomly.
  • Windows should now remember your previous login type. For example, if you log in with a PIN – it will prompt you for a PIN next time instead of another type.
  • We fixed an issue where Tab previews in Microsoft Edge were appearing as black if the page was not scrolled to the top, and web note clippings were also appearing as black.
  • Small form-factor devices, like the Dell Venue 8 Pro, that boot with rotation or virtual mode screen size set larger than the physical screen size should no longer experience a bluescreen on upgrade.
  • Apps and games should download from the Store more reliably.

I am looking forward to returning home and getting this latest build installed on my HP Stream 7 which has been sitting idle over the last two builds due to the resolution related install bug.

Microsoft has not confirmed that build 10586 is also the final Threshold 2 build however, if you remember back to when Windows 10 was released in July, Insiders received what would ultimately be the final release build two weeks prior to its official release on 29 July.
