Microsoft started pushing Windows 10 Mobile 10586.63 update tothe Fast Ring members of the Insider program. After some earlier hiccups, the updatehas now resumed again.

Earlier today, Microsoft released Windows 10 Mobile build 10586.36 to the Insider program. While some users did receive the update, several others didn't. Turns out, the update facedsome issues on the deployment servers and had to be pulled back. Gabe Aul tweeted,

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 theupdate.

Wepaused 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.

Since there was no problem with the build itself, but one with the servers, there should be no more concerns about this build. The update doesn't bring any major changes to the operating system and seems to be a usual bug fixer and performance enhancer release. With no changelogoffered, you will have to check the new build for yourself to spot any differences. If you are registered to the Windows Insider Program's Fast Ring, go toSettings>Update & Securityand click onPhone Updateto see if the latest cumulative update is available to you through the Windows Insider app. All the members are expected to receive the update today on their Lumia devices.
