That is the new "WinStep Full" program and (I believe) one of it's default skins.
The menus may or may not be customized that way with the default skin. If not, then that is either a skin made by someone, or that persons customized menus.
The clock and meters, etc. are part of the same suite of programs (either WorkShelf or NextSTART) - both of which are in the WinStep Full program.
