The latest Windows 10 Mobile Anniversary update cumulative update release Build is the Build 14393.351. It has been released to only insiders in Slow and Release Preview rings. Microsoft may release next Anniversary update build to non-insiders on November 8, but testing of newer builds will continue with help of insiders in Slow and Release preview rings.

We last reported about appearance of the Windows 10 Mobile / PC Build 14393.443. Now a newer Anniversary update CU build has appeared on the site BuildFeed that tracks internal builds under testing at Microsoft. The Build in question is Build 14393.445 and has been compiled on October 27. So, it has been under testing for only one day.


As the jump in Build number suggests (Build 14393.445 over Build 14393.321), there may be lots of fixes and improvements coming with this build. While Microsoft may release an even newer build to non-insiders on November 8, Build 14393.445 may be the one. It may come to Insiders first and on the basis of feedback from them may become the release candidate.
