The dozen or so times I allowed windows to update a video driver i ended up with 640X480 and 8 colors. Like running windows 3.0 on a 24 inch LCD screen. Best to not let the customer see that.
Easy enough to roll back, if someone has been smart enough to enable restore points.
For other drivers I really haven't "updated" from windows but more like "installed" missing drivers after doing a clean reinstall of the system. That is very convenient. I wish literally every driver there is would be made available this way.
