Windows 10 build 11073 is an internal build of the Windows 10 Anniversary Update. The language packs for this build's Spanish and Catalan localizations (alongside the associated .NET Framework 3 on-demand package) were unintentionally published onto Windows Update servers in early December 2015.

It is the last known build to include the "Microsoft Confidential" watermark primarily seen throughout Windows 8 development, as the next known compile would completely remove all of its associated shell functionality and localization resources.
