The registry path critical for changing taskbar window display settings via a script in Windows 11 is: HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Advanced\\VirtualDesktopTaskbarFilter. This registry key can be modified to change whether all windows or only those from the current desktop are shown on the taskbar. The specific DWORD value to be set can be either 0 (show windows only from the current desktop) or 1 (show windows from all desktops).
