Windows Update Makes S Series MK1 Controllers Unrecognized in Komplete Kontrol


Reid Rosefelt
"Dear Customer" email from Native Instruments:

We are currently investigating an issue that affects our TRAKTOR KONTROL S4 Mk2, MASCHINE STUDIO, and all KOMPLETE KONTROL S-Series Mk1 hardware. Following the latest updates to Microsoft Windows 7, 8, and 10, these controllers are no longer recognized.

The issue was introduced in the most recent Windows update. We are in contact with Microsoft to try to narrow down the cause and find possible solutions. Until there’s a permanent fix, you’ll need to roll Windows back to the previous version in order to keep using your hardware. We’ve created a support page showing you how to do this:

Windows 10

Windows 8

Windows 7

We apologize for any inconvenience caused, and hope to resolve the issue very soon.

Best wishes,

The Native Instruments team

Rather than follow these instructions, I found it simpler to do a System Restore to before the update, and then turn off Automatic Updates. I sure hope they fix this soon.


I've been hit by this and I'm on Windows 10 Home so I can't turn off the updates. I'm left with trying to uninstall the update every time I reboot. Plus I think I lose the option to uninstall after 10 days.

What Native Instruments fail to say in their email and support section is that if you're not on Windows 10 pro you're pretty much screwed. They don't even tell you that their recommendation only works in Pro.


Big NKS Fan !
Win10 Pro latest; Reaper 64 latest; S49 Mk1.
Symptoms quite different. S49 works somewhat normally, recognized by Reaper Audio, is NOT recognized by Komplete Kontrol latest. When Expression Pedal seemed to work incorrectly (not continuous), Komplete Kontrol displays all 'S' devices, but all greyed out; none selected/selectable.

Tried uninstalling Controller Editor, back to 1.7,4, then Update in Native Access to current 2.3.2. (per one NI Support instruction). Problem remains.

I only tested mine quickly in Komplete Kontrol standalone. I'll check in Reaper tomorrow if I get a chance. On win 10 home with S61 mk 1.

I got the 2019-02 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4487017) and after installing it my Komplete Kontrol is not working :/

So I am having uninstall it again, but I am not sure what the latest update is meant to be since NI have not supplied the name of the KB for reference!

Thanks man, I turned on my Security Updates again in Updates, which pulled down the new KB that fixed it :)

Left it off for one month as I was unsure who was going to fix the issue first ;)

UPDATE: After all I have to admit that with a few Powershell scripts and some Local Group Policy tweaks... Windows 10 Pro can be a dream :cool:
