Build 10581.1

Some interesting tidbits about Windows 10 Mobile RTM (Public Release too) dates and the probable Public Release build number. As per our sources, Microsoft is going to sign-off Windows 10 Mobile RTM build very soon. It may be signed off as early as next week and the RTM build number may be Build 10586.

Microsoft may release this build very soon to Windows Insiders before releasing it to general public. As to when this RTM build may hit Windows Phone 8.1 devices, we hear mid to end of November timelines, but it may still depend on carrier testing and approval in some markets.

Windows 10 Mobile Build 10586 isn’t supposed to bring many new features as compared to the current preview build, Build 10581, but it will be more stable and polished.

Microsoft may release both Windows 10 PC and Mobile versions of Build 10586 for testing to Insiders simultaneously.
