Hi there,
I recently got an Aquacomputer Quadro fan controller and love it. I was however very unhappy about the Eject QUADRO button that appeared in my taskbar system tray. Being the OCD person that I am, I worked out how to prevent this button from ever appearing again. And so can you, in just 15 simple steps!

This guide is written for the Quadro, but if you're looking for help with an octo, literally just replace the word quadro with octo whenever it comes up and you will be good to go.
To be clear, here is an image of what we are looking to get rid of (thank you
DMorcheti for this):
Requirements for this guide are
nssm (to make a service that runs on startup), use of notepad.exe to make a bat file, the registry editor and the command line with administrator access.
- Go to Device Manager via the start menu -> Universal Serial Bus Devices -> QUADRO -> double click (or right click and select properties).
- Select Details and then in the dropdown select Device instance path, copy the value.
- Open up Registry Editor from the start menu. In the bar at the top type
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\
Then paste the Device instance path you copied earlier. Hit Enter.
- Double click on the Capabilities entry, and set the value to 94.
- In the top right corner, click File -> Export... -> name the file "quadro-fix" and save it to your desktop.

- Create a folder called "quadro-fix" somewhere permanent (e.g. your documents folder) and move quadro-fix.reg inside.
- Create a new text document, edit it with notepad.exe and add this line:
regedit /s "C:\path\to\quadro-fix\quadro-fix.reg"
Make sure you replace path\to with the path to your quadro-fix.reg file.
- Hit File -> Save As -> name the file quadro-fix.bat (make sure it saves as a .bat file and not a .txt file). Save it in the quadro-fix folder.

- Go to https://nssm.cc/download and download the Featured pre-release version (or whatever is the newest version/compatible with your system).
- Extract the folder from the zip and place it in C:\Windows\System32
- Open up a command line with Administrator access and type
cd C:\Windows\System32\nssm-2.24-101-g897c7ad\win64
Hit Enter. (Replace win64 with win32 if on a 32 bit OS. Also change nssm-2.24-101-g897c7ad to whatever the folder containing nssm is called).
Then type
.\nssm install quadro-fix
Hit Enter. The NSSM service installer window will open.
- In the NSSM window, click on the ellipses button next to the Path: field and select your quadro-fix bat file.

- Under details, make sure the task is set to Automatic, set the Display name to Quadro Fix and give a description if you like.
- Under Log On, select This account and then fill in your Windows username and password. There are two entries for password, fill them both in with the same thing (it's to confirm you got the password right).
- Finally, select the Install service button. Restart your computer, log in and bam! The Eject QUADRO button is gone. Woooooo!
Once the service is installed, you can check it's there in services.msc. It should be called Quadro Fix/Octo Fix or whatever you named it under the Display name in nssm. It might throw an error if you try to manually start it, but that's fine. It is still running the registry edit, and will simply pause after doing so.
I hope this guide helps you, alleviates your OCD tendencies and helps you feel better about your future as a whole! Let me know how it goes, or if you need any help.
