Windows Longhorn build 4059

Windows Longhorn build 4059 is a build of Windows Longhorn. A reference of this build was found in the  file, located within the reference source code for the .NET 4.5.1 version of Windows Presentation Foundation. It mentions that builds after 4059 always display the view header regardless of the view mode being used in Explorer. This is consistent with the behaviour shown in later builds of Longhorn.
