Is it possible to "bulk" edit/pin/unpin items directly in the Start11 list? i.e. not selecting them one at a time and selecting the action via the right click dropdown
It depends on what menu style you are using
Win 7 and Modern
https://support.stardock.com/space/SHC/1335820295/How+do+I+backup+Start+Settings%3F#Windows-7/Modern-Start11-Menu-Style-Shortcuts
Win10 Style:
\HKEY_CURRENT_USER\Software\Stardock\Start8\Start8.ini\GroupContents\$PINNEDDEF$
Other styles
\HKEY_CURRENT_USER\Software\Stardock\Start8\Start8.ini\GroupContents11\$$APPS$$
If you are testing adding \ removing pins, be sure to F5 to refresh the Regedit after each.
