Windows Editions : Pro or Enterprise (Home editions not tested)

Merging highly recommends you "defer feature updates" in Windows 10, see Updates section below.

1.BIOS

If you can access your computer BIOS, it is recommended to disable all power management features of your CPU, as this implies changes in the CPU speed and that is far from optimal for any audio application.
Same applies to overclocking.
Please have a look at your motherboard manual to locate those settings, may vary depending of the manufacturer.
Intel Turbo Boost Technology: Disabled
CPU Enhanced Halt (C1E): Disabled
C-State Support (C3, C6, C7, C8 State): all Disabled
CPU EIST Function: Disabled (also called Intel Enhanced SpeedStep, that should always be disabled)
CPU power saving mode: Disabled

MassCore users : Secure Boot option is not supported, please disable this feature in your BIOS.

2.WINDOWS CONFIGURATION

During Windows installation, please take the time to customize your installation and select the required additional features.
Diagnostic Data to Microsoft can be set to "Basic".

If you don’t have a Microsoft account, you can click on “skip this step” at the bottom of the page when Windows prompt you for your Microsoft account.
Merging recommends you don’t activate Cortana now, but configure it later once the OS is installed.
Version 1809/1903 only:
Select "Offline Account" to use a standard local account rather than an online Microsoft account.

A note on drag & drop and Run as Administrator in Windows 10.

In Windows 10, when you run a program by forcing it in “administrator mode” / “Run as administrator”, drag & drop to and from this application will be disabled.

DEVICE DRIVERS

Merging recommends to install WHQL (Driver certified by Microsoft) or if not available, the latest drivers from the manufacturer website.

Install the drivers ONLY, do not install the utilities it can cause much trouble.
Do not install Intel® Control Center that is included in Intel® Rapid Storage Technology installer or Intel® Management Engine installer.
WARNING: Since PMX V11/ Ovation V7, MassCore users running a RAID configuration must use a dedicated RTX dongle (SSK-HUD-RTX) to authorize MassCore.
This issue only affects the system (Windows ) RAID drives, if you have RAID Data drives, a dedicated dongle is not required.
Do not install the RealTek Ethernet Diagnostic utility.
For MassCore users : do not install Intel® Advanced Network Services included in Intel® LAN driver, it may slow down the whole system.

GRAPHIC CARD DRIVERS
Please install your graphic card driver.
It is mandatory to configure the driver according to the Merging Graphic Cards recommended settings page.
Not properly configured drivers may trigger glitches and drops !

WINDOWS CONTROL PANEL

To access Windows 10 Anniversary (1607) Control Panel, right click on Windows Start and select Control Panel.

This can be set in Search > Searching Windows : Enhanced mode.
Since 2004, a new Indexer Performance - Respect device Power Mode Settings is available. Merging recommends you let this setting to Off, as this will increase CPU consumption.

Update & Security

(In Windows 10 Anniversary, Windows Defender is only accessible through Windows Control Panel > Windows Defender.)
Full Virus Scanning should not run at the same time as Merging software.
If you plan to install an Antivirus software, Windows Defender will be disabled.
You should also disable scanning of the Pyramix files (pmx, pmf, pml, pad, pmw) but also media files (wav, aif, flac, mp3,...), because each time the DAW have to access such file, your antivirus may scan it.
AVAST has already caused a lot of problems with several Merging programs, it is therefore not recommended.
See this page for help on configuring your antivirus exceptions.
Windows Defender users can download and run a script to include the required rules in Windows Defender.
MTWindowsDefenderExclusions.zip

Windows Defender automatic scans have to be configured in Windows Task scheduler.
Go in Windows Control Panel > Administrative Tools > Task Scheduler.
Browse the Task scheduler library to Microsoft > Windows > Windows Defender.
Right click on the Windows Defender Scheduled Scan task and select Properties.
in the Conditions tab, set it to Start only if the computer is idle, and Stop if the computer ceases to be idle.

in Windows Settings > Update & Security, select Windows Security.
In Virus & Threat Protection > Virus & Threat Protection settings, the Controlled folder access feature should be left to default.
In App & browser control, the Exploit protection feature should be left to default (some third party drivers may not install otherwise)

ADDITIONAL CONFIGURATIONS

Cortana configuration

Cortana can be disabled (recommended but optional)
In Windows Search field, type GPEDIT.MSC
Right click on the gpedit.msc and select Run as Administrator
Browse to Computer Configuration > Adminsistrative Templates > Windows Components > Search and set Allow Cortana to disabled.

If you want to keep Cortana, please configure it :
Fall Creator (1709) / Spring Creator (1803) / October 2018 (1809) :
Cortana can be configured through Windows Settings > Cortana.
In the Talk to Cortana page, set "Let Cortana respond to Hey Cortana" and"Use Cortana even when my device is locked" to off.
In Permissions & History, set "Windows Cloud Search" to off. Turning off ""View activity history", "My device history" and "Activity recommendations"(1809 only) is optional.

Cortana can be configured through Windows Settings > Cortana.
In the Talk to Cortana page, set "Let Cortana respond to Hey Cortana" and"Use Cortana even when my device is locked" to off.
In Permissions > Manage the information Cortana can access from this device, Merging recommends you set all to off.
In Windows Settings > Search > Permissions & History, set "Windows Cloud Search" to off. Turning off "My device history" is optional.

Taskbar

Right click on the taskbar to access its configuration.
Merging recommends you turn off the News and interests, and disable Show Cortana and Show Taskview.
Taskview may cause glitches if used during real-time operation, it is therefore recommended to not use it while recording or other critical operation.

Windows Store Apps auto-update

Merging recommends you disable the auto updates on Windows Apps, for better performance.
Open Windows Store, and click on the profile icon on the top right corner and select settings (On Spring Creator, click on the ... icon)
Set “Update apps automatically” or "App updates" (depending on your Windows Store version).

OneDrive configuration / uninstall

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.

System Recovery

To be able to use the Windows System Restore feature, you first need to configure it, in Windows Control Panel > Recovery : Configure System Restore.
You should only enable the protection on the system drive : select the system drive then click on Configure.
Set "Turn on system protection", then configure the Disk Space usage (usually around 10% is sufficient).

WinSAT

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.
If WinSAT runs during real-time operations, you can experience drop outs and CPU/Core peaks, therefore Merging recommends you disable it, or configure it to run only if the system is idle.

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.

If you don't want to disable it, access its Properties, then in the Conditions tab, set it to Start only if the computer is idle, and Stop if the computer ceases to be idle.

Laptop – Battery saver

Windows 10 introduces a new battery saver feature that conserves your PC's battery by limiting background activity and adjusting hardware settings. This feature can cause serious performance issues.
Merging recommends you disable the Battery Saver during recordings and critical real time operations.
Go in Windows Settings, and select System > Battery.
Set Battery saver is currently to Off.
This setting will be grayed out if the PC is currently plugged in to AC.
You may still set the Battery saver on if your battery falls below a specified %.
Activate the “Turn battery saver on automatically if my battery falls below” and set a value (Merging recommends 10 %).

Laptops usually have small graphical resources, Merging recommends you pay extra caution when using the Fixed Cursor option.

WINDOWS DEVICE MANAGER

Ports (COM & LPT)
If you use 9pin-RS422 connection:
Communication Port (COM x) > Properties
Ports Settings tab > Advanced > set both Receive and Transmit buffer to Low (4)

Universal Serial Bus controllers

Check each USB Root Hub / Host controller and disable power management if any, by right clicking on it and accessing its properties.(Power Management tab)

Network Adapters
Right click on your network adapter and access its properties to disable the power management features:

Disable Energy Efficient Ethernet and Green Ethernet, and all Power Saver / Power management features.

RAVENNA ASIO users have to set WOL & Shutdown Link Speed to Not Speed Down.
For better performance, RAVENNA ASIO users should use a dedicated RAVENNA network adapter.
Find more details on this page.
Please also follow the Native recommendations from this page.

MEDIA DRIVES

By default; Windows will index the content of all drives, which allows Windows Search to work faster.
But this indexing task takes CPU power and can result in performance issue when recording.
To disable the Windows indexing, open My Computer, right click on the Media Drive(s) and select Properties: disable Allow files on this drive to have contents indexed in addition to file properties checkbox.
NEVER USE “Compress this drive to save disk space”.

External drives: access your external drive properties through Windows Device Manager and set it to optimize for performance.

Format block size: if you only use audio files, the best size is 64 Kb when formatting the drive.
But if you also need to use video files, 64Kb is not the optimal size, in that case keep the Default Allocation size (128Kb).
The best way is to use separate drives for video and audio, if possible.

SYSTEM CONFIGURATION (MSCONFIG)

Many installed programs have associated background services, which usually can then start faster, or get updates automatically. But this uses memory and CPU power, so you should only run useful programs.

!!!Be careful, if you remove an essential program or service, Windows may not start anymore !!!
Windows Control Panel > Administrative Tools > System Configuration:
The boot menu timeout can be changed in the Boot tab (min 3 seconds).

Services Tab

Check the box Hide all Microsoft services, those are critical for Windows.
Service Bonjour is critical for RAVENNA networks and Virtual Transport.
Do not disable your graphic card and ASIO card driver or service.
Common services that can be disabled are: printer services, Skype, QuickTime updaters ...

Startup

Open the link to Task Manager to access the list.
Do not disable Microsoft Windows Operating System or any other critical driver – program for your system.

Common programs that can be disabled are Adobe Reader, Java updater, Skype, QuickTime...
Those programs will be still be installed and accessible, but will not be loaded during Windows startup.

WINDOWS UPDATE

One of the main issue with Windows 10 is that Microsoft wants the OS to always be up to date.
That means, by default, you do not have control anymore if you want to apply updates or not.
As in previous versions, sometimes an update can go wrong, and Windows can become unusable.
Hopefully it is still possible to get control under the hood.
Please note that it will only works on Pro or Enterprise versions, not on Home editions.

Automatic Updates configuration

If you want to follow the Microsoft update policy, you should at least defer the Windows updates.

Merging highly recommends you defer updates in Windows 10, as major Windows updates can make your system unusable.
This allows such updates to be further tested and approved by Microsoft, and Merging.
Updates can be configured on Pro, Educational or Enterprise editions of Windows, not on home versions!
You may also rather Pause the updates for 30 days, follow this page for detailed instructions.

Prevent Windows 10 update to new Major version

Since Windows 1803, it is possible to prevent Windows 10 to upgrade to a new major version.
Such update will not be automatically downloaded and installed on your computer, but it is still possible to update manually, with Microsoft Update Assistant.
(MassCore users should first make sure that the MassCore engine is compatible before upgrading to a new Windows version - see this page).

Please note that Merging can't guarantee that this setting will continue to work with new Windows 10 versions.
According to Microsoft "it will work until the policy is changed to a newer Windows 10 feature update.”

Download and extract the following zip file
Double click on the WindowsTargetReleaseVersionInfo.reg file to add it to your Windows registry
Open Windows Registry Editor (Regedit.exe) and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Double click on WindowsTargetReleaseVersionInfo and enter your current Windows version.
You can easily get your current Windows version by typing winver in Windows search field or Run command.

Note for MassCore users above 22H1

MassCore users with the latest Windows 10 versions will still have a warning message upon opening Pyramix.
This is due to a no longer present registry key checked at Pyramix's launch. To remedy this :

Download the "Branch Readiness Level" key : https://download.merging.com/beta/SupportTools/MTBranchReadiness.zip
Extract the zip
From Windows search, open "regedit" as administrator
Click "File>Import>Select the unzipped key"
Hit ok

Feature vs Quality updates ?

Quality Update provides fixes but no new functionality while the Feature Update provides new features.

You can also configure Windows to restart outside of active hours :
Go in Windows Start > Settings > Update and security > Windows update.
In Update settings, click on Change active hours and set it according to your needs.
This prevents Windows to restart the computer, but it still downloads the updates.
Go now in Advanced Options, and check the "Defer feature updates" : this will defer updates, allowing only widely tested updates to be applied on your computer.
Click on the "Learn more" button for further details.
Defer Updates is highly recommended, as several big feature updates can make your system unusable.

Additional configuration

In both case, Merging recommends you disable updates from other computers (your computer can receive, but also send updates directly to other computers, costing computer resources and network bandwidth) .
Go in Windows Settings > Update & Security > Windows Update > Advanced options > Delivery Optimization.
“Allow downloads from other PCs” should be set to off.

DPC LATENCY CHECK

To handle real time application, the CPU gets a defined amount of time to perform the required tasks.
If those tasks are delayed, the result is usually drop-outs in the signal.
A common tool to verify if your computer is able to handle real-time audio was DPC Latency Checker, but the reported values are false in Windows 8 and 10.
The alternative solution is to use the LatencyMon tool,
Download the tool and install it on your computer.
You can start the test by clicking on the Play icon on the top left corner.
To get useful results, the tool should run for quite some time (10 minutes minimum).
The driver or process using the highest DPC or ISR is clearly stated in the main window.
If you have too high values, you can get more detailed information in the Processes or Drivers tab.
Don't pay too much attention to the hard pagefault resolution time (last indicator)

If you have higher values, you will have to search for the driver/ device that is causing the issue by disabling them one by one.
Remember that some devices cannot be disabled, proceed with caution.
Wi-Fi, Bluetooth, LAN specific (usually ndis.sys),USB devices, on-board audio, PCI / PCIe devices are the common culprits.
On laptops, the ACPI battery driver is also a common problem (ACPI.sys), you can try to disable (do not uninstall!) the "Microsoft ACPI Compliant Control Method Battery" and "Microsoft AC Adapter" listed under Batteries in Windows Device Manager (but pay attention to not disable any other ACPI device listed under System devices, your computer may not start anymore !)
Note on Wi-Fi and Bluetooth : If you have DPC issues related to Wi-Fi and/or Bluetooth, not only the driver might be the culprit, but also the stability of the Wi-Fi network (if the signal is not stable, the Wi-Fi adapter constantly have to work which will introduce DPC latencies) or the Bluetooth devices connected to your computer. Therefore this means that if Wi-Fi does not cause DPC issue in one place, it could in another place with unstable Wi-Fi. Same applies to Bluetooth, it may cause DPC issues with certain devices only.
Be careful if you want to use Wi-Fi and/or Bluetooth on your computer.
