I don't think the new Windows update changes much at all for getting the most performance etc out of your PC. The usual still applies - switch off the services you don't need, make sure your audio folders are exempted from your AV etc.
The biggest change in the update is the ability to manage your privacy settings at a more granular level.
But as I've said in a different thread, although the update went smoothly, there was some aftermath:
AD2 (as usual with Win updates) needed re-authorising
My Focusrite drivers needed re-installed.... four times before Windows recognised them.
My folders-as-drive mappings disappeared and had to be added again to the registry
There were no specific CbB problems whatsoever though, which is good news.
As far as switching between a game machine and a DAW is concerned, IMHO this is a bad bad idea. If you really must have your games on the same PC, then make your PC dual boot between DAW & Game mode (i.e two copies of the operating system). You want your DAW as clutter-free as possible.
