In addition to individual modifications and enhancements of UI elements, such as
ribbon tabs, ribbon panels, menus and toolbars on local computers and UI workspaces, you
can apply administrative UI workspaces and UI customizations since Release 2017, Service
Pack 0.
Administrative UI customizations and UI workspaces are provided to initially set
up the settings for client computers so that they use common UI workspaces and UI
elements. These customizations and workspaces are .xml files and
have the same structure as the corresponding individual custom files, but provide a
subset of settings to be used by all users. The files should not include
non-administrative UI settings.
