I know this doesn't work but I wish it would work like this:

I am wanting to see if the key ACE exists under HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers

RegistryKey rk = Registry.ClassesRoot.OpenSubKey(@"Directory\Background\shellex\ContextMenuHandlers\ACE", false);

Since ACE is a subkey, you should be able to do this:
RegistryKey rk = Registry.ClassesRoot.OpenSubKey(@"Directory\Background\shellex\ContextMenuHandlers\ACE", false);
If the key doesn't exist, rk will be null.
