I received a brief pop-up notice that there was an important BIOS upgrade for my Inspiron 7720 and then when I went out to the Dell Support Link there is a one paragraph stating that there is a critical new BIOS update. I had hope to read more about the update and what it required but there was nothing. So I clicked on the link, this launched a download of a file - 7720A13.exe and nothing else.
How am I to distinguish this file from a SPAMMER sending me a file?
I am seriously disappointed in the lack of information on this matter.
