Always include exact PC model in your posts... Windows Update isn't always up-to-date, especially for updates from 3rd party companies, eg Dell, including BIOS updates.  Besides, Windows Update only knows what it installed on your PC. It doesn't know what/any updates SupportAssist/Dell Update installed or that you manually installed.  So it doesn't know you have a newer BIOS than it's offering. You'll have to check the versions of those other drivers it's offering to see if they're newer/older than what you already have. What are the latest versions of those drivers on Dell's support page for this PC model? To avoid risk of a failure, you probably shouldn't allow Windows Update to install any BIOS updates.  If your PC has as a BIOS setting for UEFI Capsule Updates, you should disable that setting asap to prevent Windows Update from installing this BIOS update without warning or permission. NOTES:
When looking over Windows 10 optional updates, see attached. It gives multiple suggestions for motherboard drivers / bios downloads, but also gives a firmware update of 3.11.1, which is odd because my bios firmware currently is at 3.12.1 So my first question is why would windows suggest a predecessor to my firmware to begin with ? And Second, it then has me question the whole list here of these other components on the motherboard as being true, or necessary? Anyone thoughts on this list, thanks. [IMAGE]
