my desktop was updated to Creator's.  Game mode was turned ON when I went to check. Also 'One Drive' is back after I had disabled last year.  A few other things are added which I dont need.  Also, my Yamaha Motif midi driver was corrupted, and just needed to be reinstalled.  And, of course, I had to reregister my AD2 to my 'new' computer.  I will see what else comes up.
 
 There was a link to an article that detailed turning off unwanted MS programs that I thought was very helpful.  Does any one know if there is an updated article that discusses turning off the same sort of background services now that this 'Creators' edition is up us?   

http://www.blackviper.com/ has lots of info about most all the services.
 
And always check the scheduled tasks  lots of unneeded stuff happening. That is where onedrive was. Still an annoyance to get ride of every trace as the uninstall does not do it.
 

Ah, yes, that's it. Black viper.  I am there!  Thanks!

I had to roll back, I was having wifi problems of it seeing networks then magically all would disappear. And in Sonar I had to crank my latency buffers so high they were practically maxed out so I could mix. Rolled back and all is good with the world again, well kinda . Hope it gets figured out.

of course no one is going yo turn on Game Mode in both DAW or even CAS.
But anyway 1703 sounds really good, much better, sounds like the OS clock and HAL CPU interruption has been improved a lot, much more stable, even 0 jitters for me already, even when no any default services and drivers are disabled, perfect sound! I love that, I'm going to keep using 1703 until the fall update!
With load-balancing audio softwares and MMCSS that is the heaven! I'm afraid if it even sounds much better than Mac OS........

only "usable" Windows 10 version for me is Enterprise LTSB - no Store, no Edge, entirely different Updates schedule, pity Microsoft isn't selling it to regular people and they rather announce users can "upgrade" from Windows 10 Pro to Windows 10 S ...lol...

When will there be a "Pro-Audio mode"?

When the user base is large enough to register as an entity on Microsoft's books.

I updated to 1703 in May and it's been running very well. As other's have noticed, Game mode was defaulted to ON and several other settings had been reset to defaults.
 
Interestingly, I had to lower my ASIO buffer or it would have significant drop-outs. So there is definitely something fundamentally different about the task scheduler and IO.
 

Good to know, thanks OP.
