Avoiding MS drivers
used to be the war cry about 10 years ago...
I run an Acer and have never updated using Acer drivers. MS drivers do fine for me.
The bottom line is that the drivers probably come from the same place anyway. They go to the chipset manufacturer.
And unless you are concerned about lightning frying your system, just let it download in the background... MS Update does a good job of picking up where it left off if your connection gets interrupted.
