Eric_Vernon thanks for replying. The problem I have with that architecture is the following example: Let's say user A (an avid audio listener, but not a gamer) received a Windows update which fixed an issue they were having. Meanwhile user B, who doesn't use surround sound but is an avid gamer receives the same update.
That update had a problem where it means user B cannot play their games in an optimally performant way under common setups. Microsoft decides to push a KIR update which allows the gamer audience, such as user B, a less interrupted experience by rolling back the sound feature from the windows update.
However, in the present process, user A now does not benefit from the released surround sound fix. In an improved architecture, they would have fully benefitted from the fix early while not caring about games being affected at all - and choosing not to receive the rollback. I do understand though that this is perhaps an ideal, but as a regular user of Windows I would like to know that there is at least the option to opt in or out of specific KIR rollbacks, as it suits my usage, though may prefer to receive Microsoft appointed KIR updates if I take no action.
