Whole heap of driver updates over the last couple of days including:

1. New BIOS.
2. New video driver.
3. New Touchpad driver.
4. New DPTF driver.
5. New Wifi/Bluetooth drivers (there are two – don't know the difference?)
6. New SATA driver (not sure if applicable to SSD?)
7. Some of the Dell Systems Management utilities (I don't have these installed).

I dont see much besides new chipset and new bios, where do you see a new touchpad driver? this touchpad is still so annoying with small movements

 

On that link above under Mouse, Keyboard and Input Devices:

oh thanks
none of these drivers show up for the 64 bit version of windows 10, only the 32, so i got a failed install message on the touch pad and the video driver

 

Do I need to install these manually or does "Dell Command Update" take care of business automatically?

By the way, what is the difference between "Dell Command Update" and "Dell Update"? They seem to do the same thing? Do I need both?
