Windows 11 24H2 26100.6584 I found the ms-clicktodo: protocol while looking in the Registry (Computer\HKEY_CLASSES_ROOT\ms-clicktodo), and this happened when I put it in Run. (The message says 'Click to Do is not available on this type of device.'.) Also, it does not appear in System Components, even if you open it enough times to make it appear in the 'Recommended' section of the Start Menu, pin it to Start, and then go to its app settings (which do load, and report its version as 1000.26100.6584.0).
