Today, Windows 10 build 14393.726 is available for Release Preview Ring users in the Microsoft Update Catalog. Earlier this week, Windows 10 build 14393.726 for PC and Mobile was released to the Release Preview Ring.
According to the Windows 10 build 14393.726 changelog, this release is “only available for download through the Microsoft Update Catalog website”, and looks like it may not become available as a Production Ring update through Windows Update, we’ll have to wait and see what happens. Typically, the Microsoft Update Catalog used by IT professionals that want to install stand-alone update packages.
