According to a Tweet from Microsoft’s Gabriel Aul, Windows 10 Mobile build 10586.63 doesn’t contain any new features, instead it fixes a number of problems and a few other things “per device model.” And we can see that the build number changes from 10586.36 to 10586.63.

— Gabriel Aul (@GabeAul) January 8, 2016 Windows 10 Mobile build 10586.63 is available immediately through Windows Update for those who opted into the Insider program for phones using the Windows Insider app. The update will download and install automatically, but you can always go to Settings > Update & security > Phone update and tapping the Check for updates button. Update, January 8, 2016: It appears that Microsoft has come across and that is causing to temporarily halt the availability of the new update. However, they quickly found a solution and has resumed the roll out to the Fast ring of updates.

As you can see there aren’t major changes in this release, but some people are also noting that the new build actually feel faster and more complete, which would make sense considering that the company is close to finally release the mobile operating system to the public. If you have already checked for updates and your phone isn’t seeing build 10586.63, give it some time and check again, as rolls out are never available to everyone at once.   All content on this site is provided with no warranties, express or implied.
