How about documenting the contract for this key a bit more explicitly. What do
you think of:

  // Returns the path "Software\<PRODUCT>". This subkey of HKEY_CURRENT_USER can
  // be used to save and restore state. With the exception of data that is used
  // by third parties (e.g., a subkey that specifies the location of a native
  // messaging host's manifest), state stored in this key is removed during
  // uninstall when the user chooses to also delete their browsing data.

Done.
