I use Word and Excel from Office '97. No joke, I use it every day. "Almost" portable (shows a "missing vbaen32.olb" message, which is auto-closed by the Autohotkey launcher). It loads so fast that I sometimes suspect it's already running before I even press the hotkey to launch it

Great for automatic postinstall, as well. Even runs in every PE.
(Note: most files are from O97, some are from O97SR2, to fix the slow Excel recalc bug).
Must admit: No docx/xlsx, but that's not a problem for me.
