[SOLVED] Since Windows Fall Creators Update: SONAR has a problem to start

Since Fall Creators Update:
The first problem is: SONAR needs 2 minutes to start.
The second problem is: After starting SONAR my Blofeld Waldorf plays a permanent tone - although there is no project loaded.
The third problem: When I load any project (only audio) the Blofeld plays the next permanent tone.
  
The Blofeld has a connection via USB. AudioInterface is a Roland OctaCapture. SONAR must apparently trigger a signal via USB to the Blofeld. Maybe this is a problem of my USB-port - but why does SONAR need 2 minutes to start?
If I turn off the power of the Blofeld, SONAR needs nevertheless 2 minutes to start. This cannot be the problem.
Before this update there was no problem and SONAR starts in 3 seconds.
 
Has anyone similar problems or a solution?
 

I haven’t found anywhere to disable game mode....

For a production facility I highly recommend looking into Windows Enterprise. Updates usually come out a month or two later and with fewer bugs. The group policy and power admin features are a nice value added.
 
I've been using it personally for the past year with great success in my home studio. After helping users fix various issues over the last 9 years...the last thing I want to come home to is another fire.
 
Re: Slow Open time. Windows updates sometime change the machine ID. That usually invalidates a lot of 3rd party plug-in authorizations. This could potentially cause a delayed scan. 

I'm on Windows 7, but this might help. I've posted it in other threads, too.
 
I went through the same thing. Long start time. Long shut down time. Sluggish behavior.
 
I followed the full uninstall/reinstall routine posted to the Cakewalk site, and my problems disappeared. I have no idea why, but SPlat is now just as snappy as any other program that I use. Make sure you back up your settings for the plug menus if you use customized menus. I didn't, and had to reorganize 1000+ plugins.

hmmm..cog wheel / to turn off apps/ xbox/ and perhaps radios? and anything that can cause issues, or takes up resources...and do not let apps use, what you feel is a possible cause for interruption of devices.
 
I would check the = "services." for the xbox crap...and turn it to disable, and anything to do with it...can't remember right now, but go through the list, and double check em out, on the web for what those other services do, liken spying or telemetry sending , or collecting..auto updates, and any programs with auto updates, to set to disabled or manual...to stop the interruptions, or checking for updates while working especially MS Windows, because it holds it in memory, or ties to the notifications a bell or ticket to inform, untill you address it.
 
might want to turn off notifications also while one goes hunting for any changes MS Windows has done.
 
Might have to uninstall your audio driver and reinstall it...
 
And for the odd sounds?...check to make sure "windows sounds" have not been re-enabled, make sure all usb device hubs are not powered down by windows in device manager...uncheck the boxes that say.."Let windows turn off power for this device"
 
check for latest updates for all the system drivers , bios, and firmware.
 
Seeing as the telemetry of MS and third party people must use a connection to the world wide web, of spiders and snakes selling your info to others...and not giving anyone a dime.
 
 Bing may use internet explorer to do the dirty deed...windows sounds, and drivers for sound may be affected by the deeds doing it while it has a chance to do whatever it is doing...browsers are tied to audio devices, and notifications may call system sounds...perhaps?...look into these things also:

some of the methods used might help you hunt down the problems using "monitoring".TASK MANAGER..what is running as a service...seeing the cpu usage of...and hunt it in the services to disable if too high  a % is being witnessed.
 
 
SOMETHING MIGHT BE SENDING MIDI CHANGES?..OR NOTE?...MIGHT BE MS GM GS RELATED?
 
hope it helps.
 
Cheers.

I've got updates set to the "slow ring" mode, so I haven't got the latest creator update. I still have the selector to turn it off but I'll be doing a registry hack as soon as the new version arrives.

This is why large system IT people are staying with W7. 
Have you thought of reverting to W7? 
Otherwise the Enterprise version might be the safest bet. 

Solved:
The slow start is up to Malwarebytes (internet protection software, for example Ransomeware). Since a few days Malwarebytes blocks anything, that SONAR needs to start - maybe to authenticate the Username.
But it is strange that my second DAW is also protected with Malwarebytes and SONAR starts in 5 seconds.
