|Both Dell's Datasafe and Support Center applications recently got updated, so it's probably informing you to update your copies. Open the applications up and look for an Update button, not to be confused with Upgrade.|
Because the programs are intended to help you in case of a serious error, and they tie in with your recovery partition, I suggest you don't uninstall them.
Apologies if I don't respond to your reply immediately. I don't check this site daily, but you're welcome to PM me as a reminder.
