Installing the latest Dell Client System Update utility from support.dell.com for a Latitude 10 based on the Latitude 10's Service Tag is a very dangerous proposition.  After installing it I had it check for updates and it offered me a BIOS update; however, I'm VERY glad I looked at the details first as it offered me the A11 BIOS for the Latitude E6530 NOT A04 for the Latitude 10 (A04 is the current BIOS on support.dell.com as of 25 May 2013).  One can only hope that the BIOS upgrade code is smart enough not to fry the Latitude 10 with the e6530 BIOS, but one never knows.

Note to Dell, if you're going to offer the DCSU for the Latitude 10 you need to get a catalog out there that understands the Latitude 10 and what firmware and drivers belong to it before you're sending out replacement parts by the truckload.
