    Please explain what “Preview” means. Does it mean that the same update will get released again when it’s final? If not, and this is the only release, why call it Preview?

      We use “preview” because we release this only to RS5 and above in this release. It followed by release to all other supported OSs the following month Security and Quality Rollup release.
