I'm just mentioning it because it can perform regex searches and open .reg files for editing. This does come in handy when you create backups of the registry and later want to search some keys in that backup, copy some sub-keys from there into the current registry.
There was a time when I was fiddling a lot with the registry (I think while developing some DCOM stuff) and this helped me a lot with keeping the system somewhat clean.
