I discovered that "OPENCP" and "OPENCP /L" work on Windows 10 (to open the control panel or list and index the canonical names of the cp items). But, for me, "OPENCP name" and "OPENCP index" don't work. I had to rewrite the plugin a little to figure out the error and it seems to be "access denied". So I'm wondering if they work for anyone. For example, "OPENCP Microsoft.System" or "OPENCP 32".
