Microsoft yesterday released a new build 10586.63 for Windows 10 Mobile. But the release of the build didn’t go as smooth as planned. Namely, just some time after the build was rolled out, the company decided to pulls it, and only a small amount of Windows 10 Mobile users was able to download it. But the company relaunched the update today, and it is now available to all Insiders on the Fast Ring.

The build was originally aimed to Windows 10 Mobile Insiders on the Fast Ring, but Microsoft decided to stop the rollout for a few hours, because they found some errors in the build. Gabe Aul, head of the Windows Insider program, explained the situation further via Twitter:

“Sorry #WindowsInsiders for confusion on the new update for W10 Mobile today. During publishing of the .63 update we detected a potential issue with staging on deployment servers. Since we were partially staged, some people were able to detect the update. We paused the update to investigate, and ensure that everything was 100% ready. We’re now resuming the update and it will roll out to #WindowsInsiders in the Fast ring today,” Aul explains.

So, after Microsoft development team made sure that the build 10586.63 for Windows 10 Mobile was finally ready, the rollout started again. And now, the update is available to members of the Fast Ring.

Build 10586.63 was announced to be released on January 12th, But the company decided to deliver it a few days before. This sparked up a few theories, because releasing new builds on Friday is not a usual thing at Microsoft, and the company also didn’t provide any official info about the build.

There’s a rumor that this build is actually the upgrade version of Windows 10 Mobile, and that this is what Windows Phone users will get when moving to the new OS. And because of that, Microsoft decided to release it just to Insiders a couple of days earlier, to make sure all flaws are fixed.

On the other hand, some people believe that Microsoft decided to push a new build a couple of days earlier because users were disappointed by the fact that there was no Windows 10 Mobile builds in the first week of 2016. A few of them even accused Microsoft of breaking its promise, and not delivering ‘faster’ fast builds at the beginning of the year.

Windows 10 Mobile Build 10586.63 Features

This build primarily focuses on performance improvements, and some bug fixes. Microsoft didn’t reveal any changes officially, but some users managed to find the new features and improvements by themselves.

Here are improved and new features in Windows 10 Mobile Build 10586.63:

  • Typing on Polish keyboard in Outlook Mail
  • Turn by turn directions over Bluetooth in car
  • Battery usage with Iris Reco
  • Reliability of quick actions settings page
  • MS Band use with Cortana

Once again, this update is available to Insiders on the Fast Ring only, so if you’re on a Slow ring, or you’re still using Windows Phone 8.1, you’ll have to wait a little, until you receive the update.
