January 9Jan 9 Hello, On Windows 11 Explorer, enabling the legacy command infrastructure (via StartAllBack or Open-Shell) causes Explorer to permanently instantiate a top command surface. Once this happens, reverting to stock Win11 binaries does not remove the bar — Explorer continues to allocate the command host, which is then rendered using the Win11 WinUI CommandBar. Key observations: The bar is not drawn by StartAllBack or Open-Shell Swapping Win10 explorerframe.dll breaks the nav pane but does not remove the bar shellstyle.dll hacks (height=0) no longer apply This confirms the surface exists independently of explorerframe and classic theming I’m not trying to stop legacy commands from being registered — I’m looking for a way to suppress or collapse the WinUI CommandBar host (height/visibility/layout), even if the surface itself still exists. Does anyone know: which component owns the WinUI CommandBar layout for Explorer? or whether it’s possible to force-collapse it (analogous to shellstyle hacks in Win7–10)? Any pointers (symbols, classes, binaries) would be appreciated. Edited January 9Jan 9 by ceo54
