Microsoft last released the Windows 10 Mobile Build 14393.726 to insiders in release preview ring. Non-insiders however are at Windows 10 Mobile Build 14393.693. Microsoft has surprisingly not released a new Anniversary update build in February yet but it may do that soon.

Now the latest Anniversary update CU build, 14393.823 has appeared on the site BuildFeed, that tracks internal builds under testing at Microsoft.

The Build 14393.823 has been compiled on February 9. It marks a big jump in sub-version number over the last Windows 10 Mobile release Build 14393.693 to non-insiders. As the jump in Build number suggests there may be lots of fixes and improvements coming with this build.

Microsoft may release Build 14393.823 to insiders in coming week for testing and feedback before making it available to non-insiders.
