Looks like Rafael didn't pay much attention when updating Daemon Tools. I just updated it and the program asks you whether you want to use MountSpace or not. To my knowledge, there's no silent updates of any kind, just a mere update check, which can be disabled as well.
Checking "Don’t allow MountSpace to use my mount statistics" doesn't disable MountSpace but the only thing it does in this state is to fetch up information from the MountSpace servers about the images you add to the Image Catalog. To disable it completely you have to uncheck the "Enable Media Info panel" option:
This way the program won't establish any connection with the remote servers. Additionally, you may check the "Send anonymous usage statistics" option, which comes
disabled by default. This is very bad.
Daemon Tools sure could use some competition here. It's a shame all the other tools still are not up to its standard, save for Alcohol, which isn't much more worthy of anyone's trust.
EDIT: Aha! In the newer versions they expanded the update process, so now you can also update the program without requiring the use of an installer. It seems that the process doesn't ask any question, which may explain why Rafael missed the new feature (I get an "Invalid server error" when attempting to update, so I'm not 100% sure).
What's more, the addition of MountSpace isn't mentioned anywhere in the Daemon Tools Lite changelog, while the paid clients get the 'privilege' of being informed beforehand.
