Just wanted to add that what I hope (and pray for) in this Service Release is the ability to block driver updates. While I can understand Microsoft wanting to keep the OS up and running, it's universally known that even "new" drivers can break things and decrease performance - ex. GPU drivers.
Additionally I may not want just the driver, but also the settings package that may come with drivers directly from a vender - ex. Catalyst Control Center, NVidia's control center, a soundcard's control center.
Bottom line: let me chose the drivers I want, you (MS) can have the Windows side of the house.
My two cents.
You can already disable driver installation from Windows Update.
Search for "device installation settings" then choose "no, let me choose what to do" > click "never install driver software from Windows Update."
Some I want though, I'd like to just block the one that's the issue, not all of them.
I've pointed it out in the past in other threads and was told it didn't work? It didn't stop the driver they wanted stopped. It might have been because it had already been downloaded and in the driver store. Don't know? I thought it worked for me in the past, in Windows 8.1 anyway.
I was previously getting a ton of unwanted driver updates in Windows Update for my GPU. I selected "never install driver software from Windows Update" and I have not received any graphics driver updates from Windows since. So it definitely works (at least for me.)
