When updating Windows 10 to a new major release, some settings may get reset to their default values.
Here are the settings to check after updating to Windows 10 Fall Creator Update (1709).

Pyramix V11.0.6 / Ovation 7.0.6 and MassCore RTX3.3.1 are required to run Windows 10 Fall Creator.
Previous Pyramix / MassCore versions will not work.

Usually such Windows update performs correctly, but there are still a few cases that the updates goes wrong.
Unfortunately the System restore / Windows recovery is wiped out during this update, and cannot be used to restore the system.
To be safe, Merging recommends you do a backup of your system.

Multiple Boot users

This update will rename and potentially change the Windows Boot menu entries. You can perform a backup of your boot menu:
Download and install Visual BCD Editor.
Launch Visual BCD, and browse to Store > Backup store. Then save the file in a safe place.
Once Windows has been updated, launch Visual BCD and browse to Store > Import Store. Import the previously saved file.
Proceed with caution, Windows may not start anymore in case of wrong manipulation.
Merging will not be hold responsible in case of issues using Visual BCD Editor.



Before the update, first uninstall MassCore:

Go in MT Securty Settings > MassCore tab.
Click on Uninstall MassCore, and press OK.  Your computer will reboot.
As you will install a MassCore Engine version using the same authorization code, you will not need to re-authorize the MassCore RTX License.
You are now ready to update to Fall Creator 1709.


To update to Creator Update (1709), go on Microsoft Update page and click on Update Now.
Microsoft Update assistant will be downloaded, launch it and follow the instructions.
Your computer will have to restart several times, this can take a while.
Note : if you would rather use the regular Windows Updates mechanism, the Defer updates policy will apply, and you may not be able to obtain the latest Windows version.


To access Windows 10 Creator Update (1709) Control Panel, type "control panel" in Windows Search box.  
You can right click on the control panel icon from the search result and pin it to the Start menu or Taskbar.  

Power Options 

The "Fast Boot feature" must be disabled again, which indeed puts the computer to sleep when you select shut down.  
Click on "Choose what the power buttons do” on the left hand side of Power options page.
Then click on "Change Settings that are currently unavailable" and uncheck the "Turn on fast startup" option.  Click on Save Changes.  Note also that hibernate / sleep is not supported by MassCore engine.
This is also not supported by the Ovation / Pyramix ADR keyboard.

System > Advanced System Settings

System Protection tab
In the Control Panel >  System window > Advanced System Settings, switch to System Protection tab:
Make sure protection is turned on for your system drive.
Select the system drive and click on Configure.
Select Turn on system protection, and set a value for Disk Space Usage (usually 10% max).
Disable the system protection on the Media drive(s), as this feature only works on system files and programs.

Hardware tab
Back in the main System windows, switch to Hardware tab:
Click  on Device Installation Settings and select the “No, let me choose what to do" option.
This will prevent Windows update service to automatically change the system drivers.

Settings page can be accessed through Windows Start > Settings icon (and  + i)


Merging recommends you uninstall the "XBox Live Networking" App.


Fall Creator introduces additional options to the "People" Features.
You can disable the new People icon in the taskbar through Windows Settings > Personnalization > Taskbar > Show contacts on the taskbar : Off.


In Game Bar, set "Record game clips, screenshots..." to off, and disable "Open Game bar ..." and "Show Game bar when I play ..."
In Game DVR, set both "Background recording" and "Recorded Audio" to off.
In Game Mode, set "Use Game Mode" to off. 
In TruePlay, set "True Play" to off.


Merging recommends you disable the "Show me suggested content in the Settings app" in the General Tab.

You can now enable or disable Windows Cloud Search rather than completely disabling Cortana (=Cloud Search disabled).

OneDrive configuration / uninstall

OneDrive has to be reconfigured if it was not previously configured:
If you use OneDrive, you should configure it to not interfere in the network traffic.
Right click on the OneDrive icon   in the notification area and select Settings.
Remove "Start OneDrive Automatically when I sign to Windows" and "Display notifications when people share with me or edit my shared files".
In the Network tab, set both Upload and Download rates to Limit to : 125 KB/s (or lower).
If you don't use OneDrive, you may uninstall it in Windows Settings > System > Apps and features.


WinSAT Task should be disabled.
In Windows 10, Windows System Assessment Tool (WinSAT) is scheduled to run too often compared to previous Windows version, and this tool is not very useful.  Its main purpose is to calculate the system rating displayed in Windows Control panel > System page, but it can also re-activate some setting without noticing the user.
Therefore Merging recommends you disable it.

Go in Windows Control Panel > Administrative Tools > Task Scheduler.
Browse the Task scheduler library to Microsoft > Windows > Maintenance.
Right click on the WinSAT task and select Disable.



The update enables Windows Network Throttling, that can cause issues on the network bandwidth.
Please open Merging RAVENNA ASIO control panel, the setting will be automatically modified, and the application will give you a confirmation message.
Reboot the computer after the change has been made.
