The longer story is that this issue was addressed in the 4.5.1 release. The fix was somewhat experimental, and the anniversary update was still in the process of being rolled out. So there were two releases of Couchbase Server 4.5.1 for Windows:
Normal windows release (works with Windows 10, Windows Server, etc but not Anniversary Update)
Windows 10 Anniversary Edition Developer Preview (DP) release
Furthermore, Couchbase Server 4.6 has had a Developer Preview release of its own for a while, and that release also works with the anniversary update.
But now everything is official.
Couchbase Server 4.6 has been released
Couchbase Server 4.6 officially supports Windows 10 Anniversary Update
