Blocked traktor Drivers in windows 11

tomy_nick

Hello everyone,

today i have problem with my traktor pro…

When i plug in my S4MK3 to pc it shows me next picture: (in polish)

That's meaning: This driver was blocked.

niks4m3usb.sys doesn't meet to rules of driver

In TP4.5.0 i have red icon when i switch to Asio driver (yep, s4mk3 is already plug to my pc, and of course turned on)

I tried everything…

I disabled memory integrity, turn off list of drivers in settings of windows

i turned off signing of drivers… I don't know.

A lot of perfect tracks to play and i can't…

Last time (3 days ago) everyting worked perfectly.

Any ideas?

Please help, thank you

dw.

Hello,

have you also checked under core isolation, there is a driver blocklist somewhere, I'm not at my PC right now but it must be there. It shouldn't be blocked in the first place but it somehow is obviously.

Something must have happened during this time. Check the update history of Win11 and delete all updates from the last week step by step and test.

Yes, i turned off core isolation.

Yes, i installed in the same day update KB5083631 when i last played

Actually i can't uninstall it. Win doesnt' allow to make it.

Next discovery:

code 39: driver may be damaged or missing.

in windows/system32/drivers i have file: niks4m3usb.sys, so its not missing.

The driver may be corrupted.

Reinstall the driver that is located in.

C:\Program Files\Native Instruments\Traktor Pro 4\Drivers\Traktor Kontrol S4 MK3 ASIO Driver Setup PC.exe

You can't uninstall updates?. It looks like you don't have admin rights.

reinstalled - the same problem

i don't see even this update in list of actualisation to deleting.

This has changed in KB5083631 OS Builds 26200.8328 and 26100.8328 Preview

[Windows Driver Policy update]
New! This update improves Windows security by changing how the Windows kernel trusts third‑party drivers. Default trust for cross‑signed drivers is removed, while drivers from the Windows Hardware Compatibility Program (WHCP) and an allow list of trusted legacy drivers remain allowed. Windows audits driver compatibility for at least 100 hours and three reboots before enabling enforcement. After enforcement, a small number of cross‑signed drivers might be blocked. For more information, see the Windows driver policy and the Advancing Windows driver security blog.
