It should not need a bios update just because you set it to default values. It should be the same bios. In your bios it should tell you which bios version you have right now. If you wanted to update bios, you will need to go to the Dell driver page for your model and it should list the latest bios. But, that should not be necessary. Setting it to defaults should not change your bios version, just the OS. As for the Windows Update, I have no idea, but it does occasionally happen.
