Detect active explorer replacement (from extern)

During usage of the Jumptofolder tool some questions came up.

To support NotNull I will ask two questions (each in a separate thread):

Is there an easy and reliable way to detect (from extern) if explorer replacement is activated?

For current Windows versions, you can find out by checking the default value of

HKEY_CLASSES_ROOT\Folder\shell

It will be set to openindopus if Explorer Replacement is on.

(This could change in the future if Windows changes and requires we do something different, but I don't think it has changed since Vista or maybe Windows 7.)
