MSI / Nahimic keeps reinstalling itself on Windows 11 — permanent fix (works)

After fixing audio instability on my MSI laptop (Intel HX platform), I removed Nahimic — but it kept silently reinstalling itself. It didn’t show in Settings → Apps, yet the tray icon, services, and drivers came back, along with audio crunching.

Killing the processes didn’t work — they respawn immediately. The reason is important:

Nahimic is NOT an app.
It’s an OEM A-Volute extension driver (APO). Windows and MSI Center will always try to re-inject it unless you block it at the device-policy level.

Here’s the process that finally stopped it permanently.

# 1) Remove Nahimic cleanly (Safe Mode recommended)

Boot into Safe Mode
Device Manager → Sound, video and game controllers
Uninstall all Nahimic / A-Volute / AH4 entries ✔ Check Delete the driver software
Disable Nahimic service (services.msc)
Reboot to normal Windows

# 2) Permanently block Nahimic from reinstalling (CRITICAL)

Open Registry Editor and create this path if it doesn’t exist:

HKEY_LOCAL_MACHINE
\SOFTWARE
\Policies
\Microsoft
\Windows
\DeviceInstall
\Restrictions


Inside Restrictions, create:

Multi-String Value

Name: DenyDeviceIDs
Value (one per line):
SWC\VEN_AVOLUTE
ROOT\AVolute
ROOT\AVoluteAH4


DWORD (32-bit)

Name: DenyDeviceIDsRetroactive
Value: 1


Reboot.

# Result

Nahimic does not reinstall
No tray icon
No background services respawning
Audio stable (no startup / device-switch crunch)
Survives reboots, MSI Center scans, and Windows Update

# Key takeaway

Uninstalling Nahimic is not enough.
You must block the A-Volute device IDs or Windows will keep putting it back.

This is the same method enterprise IT uses to suppress broken OEM audio middleware.

Undervolted my Vector 16 HX AI (Ultra 7 255HX) to -80mV + Unparked Cores

Hey guys i have the MSI Vector 16 HX AI with the Core Ultra 7 255HX and RTX 5070 Ti.

I’ve been tweaking it for better temps/performance and managed to set a -80mV undervolt (Core & Ring) in the BIOS. I also disabled CPU Core Parking completely to stop the stuttering.
So far it’s been perfectly stable in games with no crashes, and temps are good.

But i want to know,

Is -80mV considered a good result for the 255HX? Since it's stable, should I try pushing it further or is that asking for trouble later?
For those who have this laptop, what values are you running daily?

MSI Katana 15 issues

I've had my katana 15 b13v for about a year and it's had issues with the keyboard from day one. I can't play games using WASD without the keys "lagging." Whenever I press a key it sometimes works with no issue but it usually doesn't register my key press until 15 seconds after I press it and then it does the action that the key would cause for double the time I pressed it. I don't have this issue with a Bluetooth mouse or the trackpad but it carries over to a Bluetooth keyboard.

I've tried to figure out why it could be happening but I can't figure out anything that would cause both wired and Bluetooth keyboards to experience the same issue. Any help is appreciated.

Edit: forgot to mention that it also had hard lag spikes while playing the red strings club but not while playing portal revolution so the issues could be related since the keyboard lag only happens with games like portal revolution.

Vector A16 HX help on problems.

hello everyone recently got my hands on the vector 16 and been loving it however I'm been faced with 2 minors issues i was hoping someone would have a fix too

1)After installed my Amd drivers I'm been getting a window system driver tab that keeps opening up even after deleting it the only way I'm been able to get rid of it is going into task manager and ending task from there.


2)After waking up my laptop my Wi-Fi would become unavailable and wont allow me to connect to any WIFI doing a restart fixes this but having to do this every time has become very tedious.

MSI Cyborg fan speed very high while gaming – is this normal?

Hi everyone,
I have an MSI Cyborg laptop and I’m a bit concerned about the fan behavior. When the laptop is idle, the fans run at around 1500 RPM, with CPU temperatures between 36–46°C and GPU temperatures around 32–38°C.

When I play CS2 (which is basically the only game I play), the CPU reaches about 68–73°C and the GPU around 65°C, but the fans ramp up to around 6000 RPM.

I’d like to know if this is normal behavior or if there might be something wrong.

MSI Vector 16 HX AI Micro-stutters are driving me crazy (Core Ultra 7 + 5070 Ti)

I have an MSI Vector 16 HX AI with the Core Ultra 7 and RTX 5070 Ti. It’s a good laptop, but I keep getting these annoying micro-stutters. Basically, random FPS drops out of nowhere, then it goes back to normal. It’s happening in Hogwarts Legacy, Jedi Survivor, BF6 etc..

I feel like I’ve tried everything to fix it:

Switching to Discrete Graphics Mode

Setting User Scenario to Extreme Performance

Disabling CPU Core Parking

Removing Nahimic audio drivers

Clean installing all display drivers

Even completely reinstalling Windows

Cleared Shader cache

Nothing works. I’m just trying to play my games and these drops are really pissing me off. Has anyone with this model (or the Core Ultra chips) found a fix for this?

The laptop won't turn on at all, and the power button briefly turns on after plugging in the charger, before shutting off again. Any advice would be appreciated.
